About the Plate & Sheet Weight Calculator

Plate and sheet are bought by weight but specified by size. Enter length, width and thickness and this calculator returns kilograms per piece, kilograms per square metre and total consignment weight for carbon steel, stainless or any custom density.

How to use it

  1. 01Enter plate length and width.
  2. 02Enter thickness in mm or inches.
  3. 03Select the material or type a custom density.
  4. 04Read weight per piece, per m² and total weight.

Common questions

How do you calculate steel plate weight?
Weight (kg) = length (m) × width (m) × thickness (m) × density (kg/m³). For mild steel a quick check is 7.85 kg per m² per mm of thickness.
Does it work for chequered or coated sheet?
Use it for plain plate. Chequered patterns and galvanised coatings add weight beyond the plain-plate calculation.

Need the material rather than the maths? Browse our steel and piping products, check the steel pipe dimensions chart or the flange dimensions chart.

This calculator is free to use and built for Indian metric practice — weights in kilograms and kg per metre, dimensions in millimetres. Omegha Steel supplies pipes, fittings, flanges and fasteners from Kolkata to projects across India; send us the sizes you have calculated and we will quote on them.
