length × width × thickness × density
Result unit: kg

Weight = L × W × T × ρ. Copper density = 8960 kg/m³. For busbars and electrical conductors.

Introduction

Calculate the weight of copper sheets, busbars, round bars, and electrical conductors from dimensions and material density. Copper has a density of 8,960 kg/m3 — heavier than steel but with superior electrical and thermal conductivity. This calculator supports pure copper, brass, and bronze. Enter your dimensions and select a material to get instant weight results for electrical engineering, plumbing, and fabrication.

How This Calculator Works

Weight = L × W × T × ρ. Copper density = 8960 kg/m³. For busbars and electrical conductors.

Copper weight = Volume x Density. Sheet: W = L x W x T x density. Round bar: W = pi x (D/2)^2 x L x density. Copper density 8960 kg/m3.

Step-by-step process:

  1. Enter your input values in the calculator above
  2. The engine converts all inputs to SI base units (meters, kg, Pa)
  3. The formula is evaluated: length * width * thickness * density
  4. Result is formatted with the appropriate unit and precision

Calculation Example

A 1000mm × 100mm × 10mm copper busbar weighs 8.96 kg.

Inputs: length=1000, width=100, thickness=10, density=8960
Result: 8.96 kg

Unit Conversion for Copper Weight

**Weight units**

- 1 kg = 2.20462 lb

- 1 tonne = 1000 kg

- 1 lb = 0.4536 kg

**Length units**

- 1 m = 3.28084 ft

- 1 inch = 25.4 mm

**Density units**

- 1 kg/m³ = 0.06243 lb/ft³

Copper density is 8960 kg/m³ (0.324 lb/in³). Weight = density × volume. Convert dimensions to a consistent unit system before computing, then convert the result to kg or lb as needed.

Frequently Asked Questions

What is the density of copper?

Pure copper has a density of 8,960 kg/m3 (8.96 g/cm3). This makes copper one of the heaviest common engineering metals — about 14% denser than steel (7,850 kg/m3) and 3.3x denser than aluminum (2,700 kg/m3).

How do I calculate copper sheet weight?

Copper sheet weight = Length(m) x Width(m) x Thickness(m) x 8960 kg/m3. For example, a 1000x100x10mm copper sheet weighs 8.96 kg. Use our calculator above for instant results with any dimensions.

How much does a copper busbar weigh per meter?

A 40x5mm copper busbar weighs approximately 1.79 kg/m (40 x 5 x 8960 / 1,000,000). A 50x10mm busbar weighs 4.48 kg/m. Busbar weight is critical for switchgear structural design and transport planning.

What is the density of brass vs copper?

Brass (C360) density is 8,500 kg/m3, about 5% lighter than pure copper at 8,960 kg/m3. Bronze is 8,800 kg/m3. All three are significantly heavier than steel (7,850 kg/m3) or aluminum (2,700 kg/m3).

How do I size a copper busbar?

Busbar cross-section depends on current capacity. Rule of thumb: 1A per mm2 for continuous duty, 2A per mm2 for intermittent. A 1000A busbar needs ~1000 mm2 (e.g., 100x10mm). Always verify with IEC 60439-1 thermal calculations and consider temperature rise limits.

How much does copper weigh per square meter?

Copper sheet weight per m2 = thickness(mm) x 8.96 kg/m2/mm. A 1mm copper sheet weighs 8.96 kg/m2. A 3mm sheet weighs 26.88 kg/m2. A 10mm copper plate weighs 89.6 kg/m2.

Is copper heavier than steel?

Yes, copper (8,960 kg/m3) is about 14% heavier than carbon steel (7,850 kg/m3). However, copper's superior electrical conductivity (100% IACS) and thermal conductivity (401 W/m.K) make it irreplaceable for electrical and heat transfer applications despite the weight penalty.
