How to Calculate

Weight (kg/m) = [H × tw + 2 × (B − tw) × tf] × 0.00785 = [300 × 7.8 + 2 × 82.2 × 13.6] × 0.00785 = 35.92 kg/m

The calculator works from the dimensions only and ignores the corner radius and flange taper, so it gives 35.92 kg/m instead of the IS 808 figure of 35.8 kg/m. For billing, use the IS 808 or mill weight.
