Rebar Weight Calc helps field crews estimate rebar weight before ordering material, loading trucks, or checking a takeoff on site. Use it to: - choose common diameter presets (6 to 40 mm) - read theoretical kg per meter with d² / 162 - calculate total weight from diameter, bar length, and count - switch to a quick mode when total length is already known - save recent estimates locally for repeat ordering or loading checks - run fully offline with no account or signal required Built for fast field decisions, not spreadsheet cleanup. Important scope note: - this app provides theoretical estimates for common metric rebar planning - actual delivered weight may vary by standard and tolerance
