How to Calculate

Weight (kg/m) = [H × tw + 2 × (B − tw) × tf] × 0.00785 = [250 × 7.2 + 2 × 72.8 × 14.1] × 0.00785 = 30.25 kg/m

The calculator works from the dimensions only and ignores the corner radius and flange taper, so it gives 30.25 kg/m instead of the IS 808 figure of 30.4 kg/m. For billing, use the IS 808 or mill weight.
