How sheet plate weight is calculated
Weight comes straight from geometry and density: work out the volume of the profile, then multiply by thickness and the material's density. For sheet plate the mass is simply width × length × thickness × density. Carbon steel is 7.85 g/cm³; that single number is why a steel part weighs almost three times an identical aluminium one (2.70 g/cm³).
The quick-reference table above is calculated for carbon steel. For any other material, use the calculator's material selector — the weight scales linearly with density, so stainless (8.0) comes out about 2% heavier than steel, and aluminium about 66% lighter, for the same dimensions.
Per-metre vs. total weight
Sheet and plate are priced and handled by the piece, so the calculator gives total weight for the sheet size you enter.
Why calculated beats a printed chart
Stock charts only list round-number sizes in one material. Real jobs use odd cut lengths, mixed materials and non-standard sections. Computing the weight from dimensions means you get the exact figure for your piece — not the nearest row on a wall chart.
