What this tool does
Steel is 7850 kg/m³, aluminium 2700, stainless around 7900, brass 8500 and PVC about 1400 — change the density and the same calculation covers any of them. The per-metre and per-square-metre figures are what you need when ordering stock or checking a lifting plan.
Formula
weight = volume × density

Limitations
- Density changes with temperature, moisture and composition. Use a value from the supplier's data sheet whenever precision matters.
- Mixing units is the most common source of error. Convert every input to the units shown next to each field before calculating.
