Sheet Metal and Tube Weight Calculator
Enter the dimensions and the material, and the calculator shows you the weight of the sheet or tube instantly, per piece or per linear meter.
Weight per piece
47.1 kg
Total weight
47.1 kg
Results are indicative, calculated with standard material densities. Manufacturing tolerances and the exact alloy composition can cause small differences from the real, weighed weight.
How the weight is calculated
Formula for sheet metal
The weight of a sheet is obtained by multiplying the length, width and thickness, all converted to meters, by the material density. For a steel sheet 2 meters long, 1 meter wide and 3 mm thick, the calculation is 2 x 1 x 0.003 x 7850 kg/m3, which is about 47.1 kg.
Formula for tube
For round tube, the annular cross-section area is calculated, meaning the difference between the outer circle and the inner circle obtained by subtracting the wall thickness, then multiplied by the length and the density. For rectangular or square tube, the inner rectangle area, obtained by subtracting twice the wall thickness from each side, is subtracted from the outer rectangle area.
| Material densities used in the calculation | kg/m³ |
|---|---|
| Steel (including black, galvanized or checker plate sheet) | 7850 kg/m³ |
| Stainless steel | 8000 kg/m³ |
| Aluminum | 2700 kg/m³ |
| Copper | 8960 kg/m³ |
Frequently asked questions
How do I calculate the weight of a steel sheet?
Multiply the sheet's length, width and thickness, expressed in meters, by the density of steel, 7850 kg/m3. The result is the weight in kilograms for one piece.
Do black, galvanized or checker plate sheets weigh differently?
All three are based on steel, so the same density is used for the calculation. The zinc coating on galvanized sheet and the raised pattern on checker plate don't change the final weight significantly.
How do I calculate the weight of a round tube?
You calculate the cross-sectional metal area, meaning the area of the outer circle minus the area of the circle left after subtracting the wall thickness, then multiply by the tube's length and the material density.
How do I calculate the weight of a rectangular or square tube?
Subtract the inner rectangle area, obtained by subtracting twice the wall thickness from each side, from the outer rectangle area. Multiply the result by the length and the density to get the weight per linear meter.
Is the calculated weight exact?
The result is indicative, calculated with standard densities. Manufacturing tolerances and the exact material composition can cause small differences from the real, weighed weight.
