Weight Calculation
How is the weight of Concrete Round Bar calculated?
Round bar weight (kg/m) = π / 4 × diameter² × density / 1000. One metre of Ø30 mm Concrete Round Bar weighs about 1.696 kg.
What is the density of Concrete?
The density of Concrete is taken as 2.4 g/cm³ (2,400 kg/m³).
Concrete Round Bar weight table for standard sizes
| Size (mm) | Weight (kg/m) |
