MS Plate Weight Calculator
Work out the weight of a mild steel (MS) plate or sheet in kilograms or pounds. Enter the thickness, width and length, and the calculator shows the weight per piece and for the whole order.
Theoretical weight from nominal sizes. Actual weight varies with mill tolerance and, for rolled angles, channels and beams, the corner radius. Steel price in the UAE today: see the current price per ton.
MS plate weight formula
Weight (kg) = length (m) × width (m) × thickness (mm) × 7.85. The 7.85 is the density of mild steel in g/cm³, so every 1 mm of thickness weighs 7.85 kg per square metre.
Example: a 2000 × 6000 × 10 mm plate weighs 2 × 6 × 10 × 7.85 = 942 kg. A 1220 × 2440 × 1.5 mm sheet weighs 1.22 × 2.44 × 1.5 × 7.85 = 35.1 kg.
In imperial units, steel plate weighs 40.84 lb per square foot for each inch of thickness, so a 1/4 inch plate is about 10.2 lb/ft².

Plate, sheet or coil?
Steel under about 3 mm is usually called sheet and is sold in 1220 × 2440 mm (4 × 8 ft) or 1250 × 2500 mm sizes or cut from coil. Thicker material is plate, commonly 1500 × 6000 mm or 2000 × 6000 mm in the UAE. The weight formula is the same for both. For galvanized (GI) sheet, the zinc coating adds a small amount; for stainless steel use 7.93 g/cm³ (grade 304).

Frequently asked questions
How do I calculate MS plate weight?
Multiply length (m) × width (m) × thickness (mm) × 7.85. A 2000 × 6000 × 10 mm plate weighs 942 kg.
What is the weight of a 10 mm steel plate per square metre?
78.5 kg per square metre, because 10 mm × 7.85 = 78.5.
How much does a 4 × 8 ft steel sheet weigh?
It depends on thickness. A 1220 × 2440 mm sheet weighs 23.4 kg at 1 mm, 35.1 kg at 1.5 mm and 46.7 kg at 2 mm.
What density is used for MS plate?
7.85 g/cm³ (7,850 kg/m³), the standard density for mild and carbon steel.
Why does the real plate weigh more or less?
Mills roll plate within a thickness tolerance, so actual weight can be a few percent above or below the theoretical figure.
