To convert the result from pounds to kilograms, multiply by 0.4536. To convert density from lb/ft³ to kg/m³, multiply by 16.0185. ### Common Dimension Conversions - 1/8 inch = 0.0104 ft - 1/4 inch = 0.0208 ft - 3/8 inch = 0.0313 ft - 1/2 inch = 0.0417 ft - 3/4 inch = 0.0625 ft - 1 inch = 0.0833 ft - 2 inches = 0.1667 ft - 4 inches = 0.3333 ft ## Complete Material Density Table | Material | Density (lb/ft³) | Density (kg/m³) | Category | Calculator URL |

Nylon 6 is easier to mold and slightly less rigid. Glass-filled nylon (GF30) adds 30% glass fiber for higher strength and stiffness. Oil-filled nylon (Nyloil/Nylatron) has built-in lubrication for bearing applications. Q: What is the density of nylon in kg/m³? A: Standard nylon has a density of 1,140 kg/m³ (71 lb/ft³ or 1.14 g/cm³). Glass-filled nylon is about 1,350-1,410 kg/m³. For comparison, water is 1,000 kg/m³, so nylon just barely sinks — it's only 14% denser than water. **Polycarbonate** (https://procalc.ai/construction/polycarbonate) Q: How much does polycarbonate weigh per cubic foot? A: Polycarbonate has a density of 75 lb/ft3 (1201.4 kg/m3). This means one cubic foot of polycarbonate weighs 75 pounds. Q: How do I calculate the weight of a polycarbonate sheet? A: Multiply length x width x thickness (all in feet) to get cubic feet, then multiply by the density of 75 lb/ft3. For example, a 4x8 ft sheet that is 0.25 inches thick: 4 x 8 x 0.0208 = 0.667 ft3 x 75 = 50.0 lbs. Q: What is polycarbonate commonly used for? A: Polycarbonate is commonly used for Safety glazing, Greenhouses, Signage, Machine guards. Q: How does polycarbonate weight compare to steel? A: Polycarbonate weighs 75 lb/ft3 compared to carbon steel at 490 lb/ft3. Polycarbonate is 85% lighter than steel. **Styrofoam (EPS)** (https://procalc.ai/construction/styrofoam) Q: How much does Styrofoam weigh per cubic foot? A: Standard EPS (expanded polystyrene) weighs about 1.0 lb per cubic foot. However, density varies by grade: Type I EPS is 0.90 lb/ft³, Type II is 1.35 lb/ft³, and high-density Type IX is 1.80 lb/ft³. Extruded polystyrene (XPS, like blue or pink foam board) is denser at about 1.5-2.2 lb/ft³. Q: How do I calculate Styrofoam weight? A: Use Weight = Volume × Density. For standard EPS at 1.0 lb/ft³: a 4×8 foot sheet at 2 inches thick = 4 × 8 × 0.167 = 5.33 ft³ × 1.0 = 5.3 lbs. Always check the specific EPS grade — density can double between Type I and Type IX. Q: How much does a 4x8 sheet of foam insulation weigh? A: A 4×8 foot EPS foam board at 1 inch thick weighs about 2.7 lbs (standard density). At 2 inches thick, about 5.3 lbs. At 4 inches thick, about 10.7 lbs. XPS (extruded) boards are heavier: a 4×8 foot, 2-inch XPS board weighs about 8-12 lbs depending on brand. Q: What is geofoam and how much does it weigh? A: Geofoam is large EPS blocks used as lightweight fill in road and bridge construction. It weighs 0.70-2.85 lb/ft³ depending on grade — roughly 1% the weight of soil. A standard geofoam block (4×4×8 feet) weighs 128-365 lbs, replacing 7,500+ lbs of compacted fill at the same volume. Q: What is the density of Styrofoam in kg/m³? A: Standard EPS (Styrofoam) has a density of about 16 kg/m³ (1.0 lb/ft³). High-density EPS can reach 29 kg/m³ (1.8 lb/ft³). By comparison, water is 1,000 kg/m³ and wood is 400-750 kg/m³. EPS is about 98% air by volume, which is what gives it such low density. **Teflon (PTFE)** (https://procalc.ai/construction/teflon) Q: How much does Teflon (PTFE) weigh per square foot? A: Teflon weight per square foot depends on thickness. At 1/4 inch thick, PTFE weighs about 2.8 lbs per square foot. At 1/2 inch, it's about 5.6 lbs/ft². At 1 inch thick, approximately 11.2 lbs/ft². PTFE is significantly denser than most plastics like HDPE or nylon. Q: How do I calculate Teflon weight? A: Use the formula: Weight = Length × Width × Thickness × Density. For Teflon/PTFE, the density is 134.9 lb/ft³. Make sure all dimensions are in feet — divide inches by 12 first. For example, a 12×12 inch sheet at 1/4 inch thick: (1 × 1 × 0.0208) × 134.9 = 2.8 lbs. Q: Is PTFE heavier than nylon? A: Yes, significantly. PTFE (Teflon) has a density of 134.9 lb/ft³ compared to nylon at about 71 lb/ft³. That means Teflon is nearly twice as heavy as nylon at the same dimensions. Both are engineering plastics, but Teflon's higher density comes from its fluorine-carbon molecular structure. Q: What is PTFE used for in construction and manufacturing? A: PTFE is used for chemical-resistant gaskets, pipe linings, bearing surfaces, electrical insulation, and bridge bearing pads. Its extremely low friction coefficient (0.05-0.10) makes it ideal for sliding surfaces. In construction, PTFE-coated fabric is used for tensile roof structures like stadiums and airports. Q: What is the density of Teflon in kg/m³? A: Teflon (PTFE) has a density of 2,160 kg/m³, which equals 134.9 lb/ft³ or 2.16 g/cm³. This makes it about 2.16 times denser than water and roughly 90% heavier than nylon. Virgin PTFE is slightly less dense than filled PTFE compounds. ### Precious Metal **Platinum** (https://procalc.ai/construction/platinum) Q: How much does platinum weigh per cubic foot? A: Platinum has a density of 1339 lb/ft3 (21448.8 kg/m3). This means one cubic foot of platinum weighs 1339 pounds. Q: How do I calculate the weight of a platinum sheet? A: Multiply length x width x thickness (all in feet) to get cubic feet, then multiply by the density of 1339 lb/ft3. For example, a 4x8 ft sheet that is 0.25 inches thick: 4 x 8 x 0.0208 = 0.667 ft3 x 1339 = 893.1 lbs. Q: What is platinum commonly used for?

A: Bluestone weight per square foot by common paver thicknesses: 1-inch = 13.3 lbs/sq ft, 1.5-inch = 20 lbs/sq ft, 2-inch = 26.7 lbs/sq ft, 3-inch = 40 lbs/sq ft. For a typical 300 sq ft patio with 1.5-inch bluestone pavers, total stone weight is approximately 6,000 lbs (3 tons). Q: How much does a pallet of bluestone weigh? A: A standard pallet of bluestone typically weighs 1,500–2,500 lbs depending on paver thickness and pallet size. Full-range pallets of 1-inch irregular bluestone flagstone average about 1,800 lbs and cover approximately 130–150 sq ft. Dimensional (thermal) bluestone pallets tend to be heavier due to more consistent thickness and tighter stacking. Q: How does bluestone compare to flagstone in weight? A: Bluestone IS a type of flagstone — specifically, a dense sandstone flagstone. At 160 lb/ft³, bluestone is heavier than most other flagstone varieties. Standard sandstone flagstone averages 137 lb/ft³, while slate flagstone is about 170 lb/ft³. The weight difference means bluestone pavers require a slightly more robust gravel base than lighter stones. Q: What is the density of bluestone? A: Bluestone density is approximately 160 lb/ft³ (2,563 kg/m³). This is higher than standard sandstone (137 lb/ft³) because bluestone is a particularly dense, fine-grained variety with minimal porosity. This high density contributes to bluestone's exceptional durability and freeze-thaw resistance. Q: How do I prepare a base for bluestone patio weight? A: A proper bluestone patio base must support the stone weight plus foot traffic. For 1.5-inch bluestone (20 lbs/sq ft), install a 6-inch compacted gravel base on well-draining soil, or 8-inch base on clay soil. Use process gravel (3/4-inch minus) compacted in 2-inch lifts, topped with 1 inch of stone dust or coarse sand for leveling. The base should extend 6 inches beyond the patio edges. **Ceramic Tile** (https://procalc.ai/construction/ceramic-tile) Q: How much does ceramic tile weigh per square foot? A: Ceramic tile weight per square foot depends on thickness. At 1/4-inch thick, ceramic tile weighs about 2.85 lbs/sq ft. At 3/8-inch (standard wall tile), it's about 4.28 lbs/sq ft. At 1/2-inch (standard floor tile), approximately 5.71 lbs/sq ft. These values are based on a density of 137 lb/ft³. Q: How much does a box of ceramic tile weigh? A: A typical box of 12×12-inch ceramic floor tile (3/8-inch thick) contains about 12–15 tiles and weighs 35–55 lbs depending on tile count and thickness. Larger format tiles like 18×18 or 24×24 come in heavier boxes, often 50–70 lbs per box. Always check the manufacturer's specs for exact box weight. Q: How do I calculate tile weight in kg? A: Multiply the weight in pounds by 0.4536 to convert to kilograms. Ceramic tile density is approximately 2,195 kg/m³. For metric calculations, multiply area (m²) × thickness (m) × 2,195 to get weight in kg. Our tile weight calculator outputs both units automatically. Q: What is the weight difference between ceramic and porcelain tile? A: Porcelain tile is typically 5–10% denser than standard ceramic tile because it's fired at higher temperatures with finer clay. Standard ceramic tile density is about 137 lb/ft³, while porcelain ranges from 144–155 lb/ft³. For a 200 sq ft floor at 3/8-inch thickness, this means porcelain would weigh roughly 50–80 lbs more than ceramic. Q: How much weight can my floor support with tile? A: Most residential floors are rated for 40 lbs/sq ft live load. Ceramic tile at 1/2-inch thick adds about 5.7 lbs/sq ft of dead load, plus 3–5 lbs/sq ft for thinset mortar and backer board — totaling roughly 9–11 lbs/sq ft. This leaves 29–31 lbs/sq ft for furniture and foot traffic, which is adequate for most applications. Consult a structural engineer for upper floors or heavy stone tile. **Granite** (https://procalc.ai/construction/granite) Q: How much does a granite countertop weigh per square foot? A: A 3cm (1-3/16 inch) granite countertop weighs approximately 19.4 lbs per square foot. A 2cm (3/4 inch) slab weighs about 13.1 lbs/sq ft. For a typical kitchen with 40 square feet of countertop, a 3cm granite installation adds about 776 lbs to your cabinets — verify cabinet construction before installation. Q: How do I calculate granite weight? A: Use the formula: Weight = Length (ft) × Width (ft) × Thickness (ft) × 168 lb/ft³. For common countertop thicknesses: 2cm = 0.787 inches = 0.0656 ft, 3cm = 1.181 inches = 0.0984 ft. Example: a 10-foot × 2-foot countertop at 3cm: 10 × 2 × 0.0984 × 168 = 330.6 lbs. Q: How much does a full granite slab weigh? A: A standard granite slab (approximately 5×9 feet at 3cm thick) weighs about 870 lbs (5 × 9 × 0.0984 × 168 = 743 lbs for an average slab; actual weights range 800-1,100 lbs depending on exact dimensions). Jumbo slabs (5×12 feet) can weigh 1,100-1,500 lbs. Q: How does granite weight compare to quartz countertops? A: Granite at 168 lb/ft³ is slightly denser than engineered quartz (about 140-155 lb/ft³). A 3cm granite countertop weighs approximately 19.4 lbs/sq ft compared to 16-18 lbs/sq ft for quartz. The difference is modest — about 1-3 lbs per square foot — so both require similar cabinet support. Q: How do I convert granite weight to kg? A: Multiply pounds by 0.4536 for kilograms. Granite density is approximately 2,691 kg/m³. A 3cm granite countertop weighs about 94.7 kg/m² (19.4 lbs/sq ft × 4.882 = 94.7 kg/m²). One cubic meter of granite weighs about 2,691 kg (5,933 lbs). **Limestone** (https://procalc.ai/construction/limestone) Q: How much does limestone weigh per cubic foot? A: Limestone weighs approximately 155 lb/ft³ (2,483 kg/m³) as solid stone. Crushed limestone weighs less due to air gaps between particles — typically 85–95 lbs per cubic foot for 3/4-inch crushed stone. The exact weight depends on the specific limestone variety, porosity, and whether it's solid, crushed, or powdered. Q: How much does crushed limestone weigh per cubic yard? A: Crushed limestone weighs approximately 2,500–2,700 lbs per cubic yard (1.25–1.35 tons), depending on gradation and moisture content. A standard dump truck carries 10–14 cubic yards, or roughly 12.5–18.9 tons of crushed limestone. For driveway base material, plan on about 1.35 tons per cubic yard when ordering. Q: How much does a limestone block weigh by standard sizes? A: Common limestone block weights at 155 lb/ft³: a 1×1×1-foot block = 155 lbs, a 2×1×1-foot block = 310 lbs, a standard CMU-sized block (8×8×16 inches) = 89 lbs. Large architectural limestone blocks for building construction can weigh 1,000–5,000 lbs depending on dimensions. Q: How does limestone weight compare to granite? A: Limestone at 155 lb/ft³ is about 8% lighter than granite (169 lb/ft³). For a 30 sq ft countertop at 3cm thickness, limestone weighs approximately 456 lbs versus 497 lbs for granite — a difference of about 41 lbs. Both require similar cabinet reinforcement, but limestone is slightly easier to transport and install. Q: Can my cabinets support a limestone countertop? A: A 3cm limestone countertop weighs about 15.2 lbs per square foot. Standard kitchen cabinets support 25–30 lbs/sq ft, so limestone is well within capacity. However, add a 3/4-inch plywood subtop for even load distribution, especially at sink and cooktop cutouts where the slab is most vulnerable to stress fractures. Corner cabinets supporting large overhangs may need additional bracing. **Marble** (https://procalc.ai/construction/marble) Q: How much does a marble slab weigh? A: A standard marble slab (approximately 55" × 120" at 3cm thickness) weighs roughly 850–950 lbs. Marble density is 169 lb/ft³, so a 3cm slab weighs about 16.6 lbs per square foot. A 2cm slab weighs about 11.1 lbs per square foot. Exact weight depends on slab dimensions and cut. Q: How much does marble weigh per square foot by thickness? A: Marble weight per square foot by common thicknesses: 1 cm (3/8 inch) = 5.5 lbs/sq ft, 2 cm (3/4 inch) = 11.1 lbs/sq ft, 3 cm (1.18 inch) = 16.6 lbs/sq ft. These values are based on marble's density of 169 lb/ft³ and are essential for countertop cabinet load calculations. Q: How much does marble weigh in kg per square meter? A: Marble weighs approximately 27.1 kg/m² per centimeter of thickness. A 2cm marble slab weighs about 54.1 kg/m², and a 3cm slab weighs about 81.2 kg/m². Marble density is 2,707 kg/m³. Our calculator outputs both imperial and metric results. Q: Can my cabinets support a marble countertop? A: Standard kitchen cabinets can typically support 25–30 lbs/sq ft of countertop weight. A 3cm marble countertop at 16.6 lbs/sq ft is within this range but leaves less margin than quartz (15 lbs/sq ft) or granite (18 lbs/sq ft). Add plywood subtops for extra support, and ensure cabinets are properly secured to wall studs. Q: Is Carrara marble heavier than Calacatta marble? A: Carrara and Calacatta marble have virtually identical densities since both are calcite-based metamorphic stones quarried from the same region in Italy. Both weigh approximately 169 lb/ft³. The visual differences (Calacatta has bolder veining) come from mineral impurities that don't significantly affect density or weight. **Porcelain Tile** (https://procalc.ai/construction/porcelain-tile) Q: How much does porcelain tile weigh per square foot? A: Porcelain tile weight per square foot depends on thickness. Standard 3/8 inch (10mm) porcelain tile weighs about 4.7 lbs/ft². Thicker 1/2 inch (12mm) porcelain weighs about 6.3 lbs/ft². Large-format porcelain slabs at 3/4 inch can reach 9.4 lbs/ft². Porcelain is typically 15-20% heavier than ceramic tile at the same thickness. Q: How do I calculate porcelain tile weight for my floor? A: Multiply your floor area (in square feet) by the weight per square foot for your tile thickness. For standard 10mm porcelain: area × 4.7 lbs. For a 200 sq ft bathroom with 10mm porcelain, that's 200 × 4.7 = 940 lbs of tile. Add 10-15% for thinset mortar weight. Q: Is porcelain tile heavier than ceramic tile? A: Yes. Porcelain tile is denser than ceramic because it's fired at higher temperatures (2,200°F+ vs 1,800°F) and made from finer, more compressed clay. Porcelain runs about 150 lb/ft³ compared to ceramic's 130-140 lb/ft³. At the same thickness, porcelain is roughly 10-15% heavier. Q: Can my floor support the weight of porcelain tile? A: Standard residential floor joists (2×10 at 16 inches on center) can handle porcelain tile on any floor. The combined weight of porcelain tile plus thinset is typically 6-8 lbs/ft², well within the 40 lb/ft² live load rating of most residential floors. Large-format slabs or natural stone may require an engineer's review. Q: How much does a box of porcelain tile weigh? A: A standard box of porcelain tile weighs 45-70 lbs depending on tile size and thickness. A 12×24 inch format at 10mm typically comes 8 tiles per box at about 55 lbs. A full pallet of porcelain tile weighs 2,000-2,500 lbs and covers approximately 400-500 square feet. **Quartz** (https://procalc.ai/construction/quartz) Q: How much does quartz weigh per cubic foot?
