How to Use This Calculator
- Enter the bar size number (#3 through #18) — the bar number equals the diameter in eighths of an inch.
- Set the bar length in feet (standard mill length is 20 ft, but enter cut lengths if known).
- Enter the quantity — total number of individual rebar pieces for this size and length.
- Read Weight per Foot (lbs) and Total Weight (lbs) for material takeoff and load calculations.
- Use Total Weight (kg) if your supplier quotes in metric tons.
- Check Estimated Cost for budget purposes; adjust using your local market price per pound.
