Calculate rebar quantities and weights from a bar schedule

Bar schedule

Mark Ø (mm) Length (m) Qty Weight (kg)
Weights use the standard steel reinforcement formula (diameter² ÷ 162 kg/m) - a nominal mass calculation, not a substitute for a structural engineer's bar bending schedule. Always confirm laps, bends and cover with the project's actual RC design.

Nominal mass per metre from the standard formula (d² ÷ 162 kg/m). Typical-use notes are a general guide only - always follow the project's structural drawings and bar bending schedule for actual bar sizes, spacing and laps.
