Material Weight

Plate Weight Calculator

Weight of a rectangular plate or sheet in steel, aluminium, copper and more.

Inputs

Rectangular plate showing length L along the front edge, width W along the side edge and thickness t.L — lengthW — widtht
Plate with length L, width W and thickness t. Weight = L × W × t × density. Diagram not to scale.

Density used: 7,850 kg/m³ — nominal value used in steel section mass tables, e.g. EN 10210-2 and EN 10219-2 (7.85 kg/dm³).

A 2,000 mm × 1,000 mm × 10 mm plate in carbon / mild steel weighs about 157 kg.

About this calculator

Use this calculator to estimate the weight of flat plate and sheet for purchasing, transport, lifting and costing. Choose a material or enter your own density. The weight is simply volume × density, so the result is only as accurate as the dimensions and density you use.

Formula

m = L × W × t × ρ

L, W, t = length, width, thickness (m); ρ = density (kg/m³); m = mass (kg).

Quick rule for steel (ρ = 7850 kg/m³): plate weight per square metre = 7.85 × thickness in mm kg/m².

Worked example

A carbon steel plate 2000 mm × 1000 mm × 10 mm:

  • Volume = 2.0 × 1.0 × 0.010 = 0.020 m³
  • Weight = 0.020 × 7850 = 157 kg
  • Check with the quick rule: 7.85 × 10 = 78.5 kg/m² × 2 m² = 157 kg ✓

Assumptions and limitations

  • A solid rectangular plate at its nominal dimensions, with no holes, cut-outs, chequer pattern or coating.
  • Densities are typical values for estimating. Your material certificate or supplier data may give a different value.
  • Rolling tolerances on thickness can make real plates noticeably heavier or lighter than nominal.

Safety note

For lifting, always use the actual weight from the delivery documents or a weighing, plus suitable rigging margins. Do not rely on an estimate alone to select lifting equipment.
