Density and weight
How much does the workpiece weigh? Enter the dimensions in millimetres and the material's density from the data sheet, and you get the weight.

Density
Steel: DS/EN 1993-1-1 clause 3.2.6 (7,850 kg/m³) · aluminium: DS/EN 1999-1-1 clause 3.2.5 (2,700 kg/m³). Use your own material's data sheet when you have it.
Find it in the material's data sheet. Water is approx. 1 kg/dm³.
Answer
Mass
47.1kg
Volume per piece
6dm³
In grams
47,100g
How to work it out
- 1V = 1,000 · 2,000 · 3 mm³ = 6 dm³
- 2m = V · ρ = 6 dm³ · 7.85 kg/dm³ = 47.1 kgMeasurements in mm give mm³; divide by 1,000,000 to get dm³, which matches the density in kg/dm³.
The formula
ρ = m / V
Density is mass per volume.
kg/m = A [mm²] · ρ [kg/dm³] / 1.000
Weight per running metre from the cross-section — as in the steel merchant's weight tables.
1 kg/dm³ = 1 g/cm³ = 1.000 kg/m³
The same density in three units.
1 dm³ = 1.000.000 mm³
Measurements in mm must be divided by a million to become dm³.
