Plate, round bar and tube weight

Material Weight Calculator

Calculate the weight of common stock shapes from dimensions, material density and quantity.

Method

How this tool works

Weight = geometric volume × density. Tube volume subtracts the inner cylinder from the outer cylinder.

Worked example

A 1,000 × 1,000 × 1 mm steel plate has a volume of 0.001 m³ and weighs about 7.85 kg at 7,850 kg/m³.

Use responsibly

Preset densities are representative values; exact alloy, moisture, tolerances, coatings and mill certificates can change actual weight.
