Calculating the weight of a piece of material

Plate, square and rectangular

To calculate the weight of a plate, square or rectangular piece of material, multiply the width, height and length to get the volume, then multiply by the "Kg /Cu. Mtr" figure for the appropriate material from the above table.

Note: Ensure that all measurements are converted to Meters.


Find the weight of a steel plate, 2m x 1.5m x 10mm thick.

1) Volume in cubic meters is 2 x 1.5 x 0.01 = 0.03 m3

2) Volume x density , 0.03 x 7850 = 235.5 kg
