## How the calculator works

| Shape | Cross-section or weight |
|---|---|
| Sheet | length × width × thickness × density |
| Perforated sheet | as sheet × (1 − open area); open area per hole pattern in the [Perforated sheet calculator](https://mvg-frankfurt.de/en/perforated-sheets#rechner) |
| Chequer plate | base thickness × density × 1.07 |
| Round bar | π × d² ÷ 4 |
| Round tube | π × (D − s) × s |
| Flat/square bar | width × thickness |
| Square/rectangular tube | B × H − (B − 2s) × (H − 2s) |
| Angle | s × (a + b − s) |
| Hex bar | √3 ÷ 2 × AF² |

Cross-section in mm² × density in kg/dm³ ÷ 1000 = kg per metre. Radii according to the standard are not taken into account; for profiles with radii the result is slightly above the standard weight. For catalogue items, every [Product page](https://mvg-frankfurt.de/en/semi-finished) the weight per metre according to the catalogue.

## Frequently asked questions about weight

**How do I calculate the weight of a sheet?**

Length × width × thickness gives the volume; times density gives the weight. A steel sheet 2000 × 1000 × 2 mm has 4 dm³ and weighs around 31.4 kg at 7.85 kg/dm³.

**How do I calculate the weight of a tube?**

For a round tube, the cross-section is π × (outside diameter − wall thickness) × wall thickness. Cross-section in mm² times density in kg/dm³ divided by 1000 gives kg per metre.

**What is the density of aluminium, stainless steel or brass?**

We calculate with the usual trade values: aluminium 2.70 kg/dm³, steel 7.85, stainless steel 8.00, brass 8.50, copper 8.96, gunmetal 8.70 and bronze 8.80 kg/dm³ – the same values as in our sheet catalogue.

**How accurate is the result?**

The calculator assumes sharp-edged cross-sections. Tubes and profiles with radii weigh slightly less according to the standard; rolling and thickness tolerances are added. The value is usually sufficient for shipping and structural calculations; the weighed result is the delivery weight.

**How do I calculate perforated sheet and chequer plate?**

Perforated sheet: weight of the solid sheet × (1 − open area). Chequer plate: base thickness × density × 1.07 for the chequer pattern.
