This transformer winding weight calculator estimates the mass of copper in a coil from the total wire length and its cross-sectional area. Enter the values above for a quick weight figure.
Formula
Weight = Length × Area × Density Copper density ≈ 8960 kg/m³
Example
50 m of 1 mm² copper: Weight = 50 × 1×10⁻⁶ m² × 8960 = 0.448 kg.

Frequently Asked Questions
How do I find the weight of transformer windings?
Multiply the total wire length by its cross-sectional area and the copper density of about 8960 kg per cubic meter.
Why estimate winding weight?
Copper is a major cost and heat factor, so winding weight helps with pricing and thermal design.
Does insulation add weight?
Slightly. This estimate covers the copper only; enamel and paper add a small extra percentage.
