Rebar Calculator
Use this rebar calculator to estimate rebar weight from bar diameter and total length.
Formula: (Diameter^2 / 162) x Length
Example
Formula: (Diameter^2 / 162) x Length = (12 mm^2 / 162) x 50 m = 44.44 kg
Enter diameter and length in any unit, then the result will be in kg.
Tip: Choose your result unit on the right before calculating.
Step-by-step calculation
- Enter bar diameter and total length with units.
- Calculate to see rebar weight in kg.
FAQ
- Why divide by 162?
- This is the standard rebar weight formula.
- Is this for one bar?
- Enter total length for all bars combined.
