    Rebar Theoretical Weight Calculator

    Calculate approximate reinforcing steel weight from nominal diameter, cut length and number of bars. The widely used D²/162.2 kg/m estimate is theoretical and is not a bar bending schedule.

    MAKE IT SIMPLE
    Assumptions and limitations

    Bar schedules, laps, bends, construction waste and manufacturer tolerances must be checked separately.
