The formula to work out the weight in Kg's of a mild steel sheet or plate:

Example: 2500 x 1250 x 5mm

Formula: 2.5 x 1.25 x 5 x 7.856 (g/cm3) = 122.75 Kg's

For guide purposes only,a formula that takes into consideration the plus tolerances used when producing mild steel sheet or plate:

Example: 2500 x 1250 x 5mm

Formula: 2.5 x 1.25 x 8 x 5 = 125 Kg's
