- 1 in = 25.4 mm
- 1 lb/ft2 = 4.88 kg/m2
Steel sheets and plates are typical stocked in 36”, 48”, and 60” widths and 96”, 120”, and 144” lengths.
Example - Weight of Steel Plate
The weight of a 1 inch thick 36" (3 ft) x 96" (8 ft) steel plate with weight 40.8 lb/ft2 (from table above) can be calculated as
W = (40.8 lb/ft2) (3 ft) (8 ft)
= 979 lb
Calculating Steel Plate Weight
Weight per sq. feet of hot rolled mild steel plates can be calculated as
W = 40.8 t (1)
where
W = weight of steel plate (lb/ft2)
t = plate thickness (in)

Steel sheets and plates are typical stocked as size 2000 mm x 3000 mm.
Weight per sq. meter of hot rolled mild steel plates can be calculated as
W = 7.85 t (2)
where
W = weight of steel plate (kg/m2)
t = plate thickness (mm)
