Step-by-step solution
What Is Rebar Weight?
Rebar weight calculation is the process of finding the per-meter and total weight of ribbed reinforcement steel. Since steel is sold by weight, it is used for quantity take-off and cost estimation.
How is it calculated?
How Is It Calculated?
Unit weight (kg/m) = diameter² (mm) ÷ 162
Total = unit weight × length × quantity
- Enter the diameter, length, and quantity.
- For Ø12: 144 ÷ 162 ≈ 0,888 kg/m.
Frequently Asked Questions
Where does the diameter²/162 formula come from?
It is derived from the density of steel and the simplification of the circular cross-section area formula.
