Formula

Volume per bar = π × diameter² ÷ 4 × length. Weight = volume × density × quantity.

Steel density

The preset uses 7,850 kg/m³. Enter the actual alloy density for a grade-specific estimate.

Scope

This calculator is for solid round bar only, not pipe or hollow tube. It estimates material weight and does not check structural capacity.
