Aluminium Sheet and Plate Weight per Square Metre: Thickness Table
Sheet and plate are priced and shipped by weight, so knowing the weight per square metre for each thickness saves time when you plan an order. The calculation is simple, and the table below covers the thicknesses most buyers ask about.
The formula
Weight per m² (kg) = Thickness (mm) × Density (g/cm³)
With the standard density of 2.70 g/cm³, every millimetre of thickness adds 2.70 kg per square metre. For a full sheet:
Sheet weight (kg) = Width (m) × Length (m) × Thickness (mm) × 2.70
Weight per square metre by thickness
| Thickness | kg per m² (2.70) | Sheet 1000 × 2000 mm | Sheet 1250 × 2500 mm |
|---|---|---|---|
| 1 mm | 2.70 | 5.40 kg | 8.44 kg |
| 1.5 mm | 4.05 | 8.10 kg | 12.66 kg |
| 2 mm | 5.40 | 10.80 kg | 16.88 kg |
| 3 mm | 8.10 | 16.20 kg | 25.31 kg |
| 4 mm | 10.80 | 21.60 kg | 33.75 kg |
| 5 mm | 13.50 | 27.00 kg | 42.19 kg |
| 6 mm | 16.20 | 32.40 kg | 50.63 kg |
| 8 mm | 21.60 | 43.20 kg | 67.50 kg |
| 10 mm | 27.00 | 54.00 kg | 84.38 kg |
Does the alloy change the weight?
Slightly. Common 1050 sheet is 2.71 g/cm³, 5052 is 2.68, 5754 and 5083 are 2.66, and 7075 is 2.81. The effect is usually below one to two percent, but for high-value or weight-critical orders it is worth using the exact alloy density, which the EAS weight calculator lets you select.
Tread (chequer) plate
Patterned plate is heavier than a flat sheet of the same base thickness because of the raised pattern. Do not use the flat-sheet formula for it; use the tread plate calculator instead.
Calculate sheet, plate or coil
Enter width, length, thickness and quantity in the sheet calculator, the plate calculator or the coil calculator to get the weight per piece, the area and the total weight. For profiles, tubes and bars, see our guide on how to calculate aluminium weight or use the main weight calculator.
Frequently asked questions
How much does a 2 mm aluminium sheet weigh per square metre?
About 5.4 kg per m² with the standard density of 2.70 g/cm³.
How do I convert between sheet weight and thickness?
Divide the weight per m² by 2.70 to get the thickness in millimetres. For example, 10.8 kg/m² corresponds to 4 mm.
