How it works
Estimate reinforcement mass from bar diameter, total length and bar count using the common metric approximation.
Core method:
Unit mass ≈ d² / 162 kg/m for diameter d in millimetres. Total mass = unit mass × total length × allowance.
Unit mass ≈ d² / 162 kg/m for diameter d in millimetres. Total mass = unit mass × total length × allowance.
Before you use the result: Check project drawings, supplier data and site conditions before ordering materials.
