Metal Weight Calculator
Calculate the weight of any metal part — steel, stainless, iron, aluminum, brass, bronze, copper, titanium — from its shape or CAD volume. Output in kg and lb.
Method
Weight = volume × density
Volume is computed from the geometry you pick, or entered directly from CAD. Densities follow standard metallurgical values.
Common metal densities (g/cm³)
| Metal | Density |
|---|---|
| Carbon steel | 7.85 |
| Stainless 304/316 | 7.93–8.00 |
| Aluminum | 2.70 |
| Brass | 8.50 |
| Copper | 8.96 |
Frequently Asked Questions
How do I calculate metal weight?
Multiply the part volume by the metal density. Volume comes from the shape dimensions or from a CAD model.
What is the density of steel?
Carbon steel is about 7.85 g/cm³; stainless is 7.93–8.00.
Can I use a custom alloy?
Yes, pick the closest material or use a custom density value.
Does it output kg and lb?
Yes, both, plus batch totals and cost if you add quantity and price.
