Current calculated steel quantity
Unit weight = d² / 162 kg/m
No. of Bars Required Calculator
Calculate the number of reinforcement bars required from total length, clear cover and spacing.
Effective length = Total length − 2 × Clear cover at each end. Number of bars = ceil(Effective length / spacing) + 1.
For site work, “Do not exceed spacing” is usually better because the actual spacing becomes equal to or less than the entered spacing.
