Rebar Weight Calculator

Need to know how much rebar to order or load? Enter a diameter and either bars × length or a known total length to see theoretical kg, metric tonnes, and an optional order/load allowance. Rebar Weight Calculator is built for a quick metric rebar planning check before an order, pickup, or truck load. Use it to: - choose common diameter presets from 6 to 40 mm - see theoretical kg per meter using d² / 162 - calculate total length and weight from diameter, bar length, and count - switch to a known-total-length estimate when the bar count is already known elsewhere - add an optional allowance for an order/load check, up to the app's supported limit - save recent estimates locally and share a summary that names the input mode and source length - work offline without an account, ads, subscriptions, or a server Results are theoretical material-planning estimates. Delivered weight can vary by standard and tolerance; confirm the final order against the applicable material documentation.
