How the Calculation Works
Weight is volume multiplied by density. With dimensions in millimetres and density in g/cm³, dividing by 1,000,000 gives kilograms.
| Shape | Formula (kg) |
|---|---|
| Plate or sheet | length × width × thickness × density ÷ 1,000,000 |
| Round bar | π ÷ 4 × diameter² × length × density ÷ 1,000,000 |
Worked example: one Inconel 625 plate, 2000 × 1000 × 6 mm, at 8.44 g/cm³ weighs about 101 kg (223 lb). Three such plates weigh about 304 kg (670 lb).
FAQ
How accurate is the weight calculator?
It gives the theoretical weight from nominal density and nominal dimensions. Real weights differ with tolerances, scale and coatings; the weighbridge weight governs every transaction.
Why do some grades not appear in the calculator?
We only list grades whose nominal density we can support from published sources. See the grade chart.
