The formula
Plate weight follows from four numbers: length, width, thickness and the material's density.
weight (kg) = length (m) × width (m) × thickness (m) × density (kg/m³)
Watch the units: this tool takes length, width and thickness in millimetres and converts to metres itself — that's where most manual calculation errors come from.
Material densities
| Material | Density |
|---|---|
| Structural steel (S235/S355) | 7,850 kg/m³ |
| Stainless steel 304/316 | 8,000 kg/m³ |
| Aluminium (5754/6082) | 2,700 kg/m³ |
These are standard values for the most common alloys. A specific alloy may vary by a few percent — for a quote we use the exact material data.
Why calculate plate weight?
A plate's weight determines how you can safely lift or transport it, what shipping will cost, and gives a first indication of material cost before a full quote is made.
