Sheet Metal Weight Calculator

Sheet metal weight formula

m = L × W × T × ρ

Total mass = m × quantity

Use L, W and T in metres and density ρ in kg/m³ to obtain mass m in kilograms. With dimensions in millimetres, divide L × W × T × ρ by 1,000,000,000. One inch is 0.0254 metres; one pound is 0.45359237 kilograms.

Example: a 2,000 × 1,000 × 2 mm carbon steel sheet at 7,850 kg/m³ weighs 31.400 kg (approximately 69.225 lb). Ten identical sheets weigh 314.000 kg. Switching dimension units converts your measurements and preserves the physical weight.

The result is theoretical mass, commonly called sheet weight. Actual stock weight varies with alloy composition and dimensional tolerances.

Choosing a material density

21 material and grade presets cover steels, aluminium, copper and copper alloys, other engineering metals and precious metals. Each preset has its own reference density. Use the Density source link beside the input guidance to check the selected material.

Choose the grade, purity and temper that match your stock. Brass and bronze densities vary with alloy composition. Use Custom density when your supplier specifies a different value. Multiply g/cm³ or kg/dm³ by 1,000 to obtain kg/m³.
