How to Calculate Rebar Weight
Reinforcing steel bars (rebar) are specified by diameter and used to strengthen concrete structures. Knowing the total weight helps with cost estimation, structural calculations, and delivery planning.
Rebar Weight Formula
Weight (kg/m) = d2 / 162
Where d = diameter in millimeters. This is the standard formula used in structural engineering.
Standard Rebar Weights
| Diameter | Weight per Meter | Weight per 6 m bar |
|---|---|---|
| 8 mm | 0.395 kg/m | 2.37 kg |
| 10 mm | 0.617 kg/m | 3.70 kg |
| 12 mm | 0.888 kg/m | 5.33 kg |
| 16 mm | 1.579 kg/m | 9.47 kg |
| 20 mm | 2.467 kg/m | 14.80 kg |
| 25 mm | 3.854 kg/m | 23.12 kg |
| 32 mm | 6.313 kg/m | 37.88 kg |
Common Applications
- Foundation slabs and footings
- Columns and beams
- Retaining walls
- Bridges and infrastructure
- Pool shells
Rebar Spacing and Concrete Coverage
Standard requirements: minimum 40–50 mm of concrete cover over rebar to protect against corrosion. Spacing is typically 150–300 mm center-to-center for slabs, depending on structural requirements and design loads.
