Weight Calculation Formula

The weight of Domex plate can be calculated using the following formula:

Weight (kg) = Thickness (mm) x Width (m) x Length (m) x Density (kg/m3)

For example, to calculate the weight of a piece of Domex 355 plate that is 10 mm thick, 2 meters wide, and 3 meters long, the calculation would be:

Weight (kg) = 10 x 2 x 3 x 7850 = 471,000 kg
