Method
A sheet weighs thickness (mm) × width (m) × length (m) × 7.85. Each square metre weighs 7.85 kg per millimetre of thickness.
The density of steel is 7.85 g/cm³ (7850 kg/m³) throughout. A number is rounded once, when shown; the table below and the calculator above are the same computation.
The "standard weight" is the nominal weight by table or formula. The "mill weight" is what that mill states for its own length; once you pick a mill, the calculation and the amount use it.

2 mm plate 1.25×2.5 m weighs 49.06 kg; each square metre is 15.7 kg. Basis: Formula t × w × l × 7.85.
For 2 mm plate 1.25×2.5 m, one tonne is 20.38 sheets of 2.5 m, that is 21 whole sheets (1,030.31 kg). For any other size use the count-from-weight mode.
The standard weight is the nominal weight by table or formula, the same for every mill. The mill weight is what each mill states for its own length. Pick a mill and its weight and today's price become the basis of the amount.
Pick a mill to see the amount at today's price, then use "Add to cart" or "Proforma". There is no online payment; an Ahantime expert calls to complete the purchase.
