Steel Plate Weight Guide: Calculator & Data Table

Steel Plate Thickness and Weight - Imperial Units

• 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)
