The formula
12² ÷ 162 = 0.889 kg/m; 156 m × 0.889 = 138.67 kg; 156 m ÷ 12 m = 13 bars.
The assumptions
- Lengths taken from your engineer’s bar schedule.
- Laps and offcuts not counted.
- A qualified engineer or architect must design and approve every structural element — slabs, beams, columns, foundations, reinforcement and load-bearing walls. Our calculations give indicative quantities and budgets, never dimensions.
How to use it
Take your engineer’s bar schedule.
For each diameter, enter the number of bars and their cut length.
