How to Calculate

Weight (kg/m) = [H × tw + 2 × (B − tw) × tf] × 0.00785 = [125 × 5.3 + 2 × 59.7 × 8.1] × 0.00785 = 12.79 kg/m

The calculator works from the dimensions only and ignores the corner radius and flange taper, so it gives 12.79 kg/m instead of the IS 808 figure of 12.7 kg/m. For billing, use the IS 808 or mill weight.
