Instantly calculate copper weight for sheets, round bars, pipes, wires and busbars. Supports pure copper C110, C101, brass C260, phosphor bronze C544 and more alloy grades. Enter dimensions in mm or feet.
Select shape, enter dimensions, choose alloy grade and get instant copper weight in kg, tonnes and lbs.
Follow these simple steps to calculate copper weight accurately in seconds for any shape or alloy
Choose from Sheet/Plate, Round Bar, Pipe/Tube, Wire/Cable or Busbar/Flat. Each shape shows only the relevant dimension fields needed for that calculation.
Select Millimetres (mm) for metric dimensions from engineering drawings, or Feet & Inches if your supplier quotes in imperial units common in export markets.
Type in the relevant dimensions for your chosen shape. For pipes enter OD and wall thickness. For wire enter diameter and length in metres. For busbars enter width, thickness and length.
Enter the number of pieces. The calculator multiplies per-piece weight by quantity to give total procurement weight and tonnage for your purchase order or logistics planning.
Choose your copper alloy from the dropdown. Pure copper C110 has density 8.96 g/cm³ while brass C260 is lighter at 8.47 g/cm³. Use Custom Density for unlisted or special alloys.
Results update live — kg per piece, total kg, kg/m², total tonnes, lbs and volume (cm³) are all shown. Use kg/m² to verify against supplier mill certificates and material datasheets.
Understand exactly how copper weight is calculated for each shape type with worked examples
Area = 2440 × 1220 ÷ 1,000,000 = 2.977 m²
kg/m² = 3 × 8.96 = 26.88
Weight = 2.977 × 26.88 = ≈ 80.0 kg
Volume = π/4 × 25² × 1000 = 490,874 mm³
= 490.87 cm³
Weight = 490.87 × 8.96 ÷ 1000 = ≈ 4.40 kg
Weight = π × (28−1.5) × 1.5 × 1000 × 8.96 ÷ 1,000,000
= π × 26.5 × 1.5 × 1000 × 8.96 ÷ 1,000,000
= ≈ 1.120 kg/m
Volume = 50 × 6 × 1000 = 300,000 mm³
Weight = 300,000 × 8.96 ÷ 1,000,000
= ≈ 2.688 kg/m

Key industries and real-world applications where precise copper weight data is essential
Copper busbars, switchgear, transformers and power cables are priced and specified by weight. Accurate kg/m figures are essential for electrical panel design, cable tray load calculations and procurement budgeting in 2026 infrastructure projects.
Solar panel wiring, EV battery packs, charging infrastructure and wind turbine windings require precise copper weight data for BOM costing, motor design and energy efficiency calculations as global copper demand for green energy surges in 2026.
Copper roofing sheets, gutters, downpipes and plumbing tubes are widely used in premium residential and commercial construction. Structural dead load calculations and materials budgeting require accurate copper sheet and pipe weight data.
Heat exchangers, pressure vessels, chemical equipment and industrial machinery use copper and copper alloy sheet and tube. Fabricators need weight per metre and total tonnage for machine load planning and freight cost estimation.
Copper-nickel alloys (C715, C706) are the standard for marine seawater piping, condenser tubes and hull sheathing due to their excellent corrosion resistance. Pipe and sheet weight calculations are critical for vessel weight and stability analysis.
Copper is one of the most traded industrial metals globally. Scrap dealers, metal traders and recyclers use weight calculations to price copper wire, pipe and sheet at LME-linked rates. Accurate kg figures directly impact transaction value.
Best practices used by engineers, fabricators and procurement teams worldwide
Brass C260 (8.47 g/cm³) is 5.5% lighter than pure copper C110 (8.96 g/cm³). On a 500 kg order this means 27 kg difference. Always confirm the UNS alloy designation from the mill test certificate before running your calculation.
ASTM B88 copper tube allows ±10% wall thickness tolerance on Type K and L tubes. For tight weight budgets, calculate using the upper tolerance wall thickness to avoid under-ordering on critical projects.
Typical copper sheet cutting and fabrication wastage is 8–12% depending on part geometry and nesting efficiency. Add this allowance when ordering raw material to prevent costly production delays and emergency re-orders.
kg/m² is independent of sheet size — use it to cross-check any supplier quotation. A 3 mm C110 copper sheet must be 26.88 kg/m². If the supplier's figure differs by more than 2%, query the alloy grade or check for measurement errors.
Tinned copper busbars have a tin coating of 5–20 microns adding negligible weight for most purposes. However PVDF-coated copper roofing sheets add approximately 0.05–0.10 kg/m². Note this for precision structural dead load calculations.
As of 2026, copper is priced per tonne on the London Metal Exchange (LME). Convert your total weight to tonnes using this calculator, then multiply by the current LME copper price to get accurate material cost for tenders and quotations.
