Stainless Steel Round Bar Weight Calculator

Summary

Select a stainless steel grade, enter diameter and length, and instantly get weight in kg and lbs.

How it works

1. Select the stainless steel grade from the dropdown — the correct density is applied automatically.
2. Enter the bar diameter and choose the unit (mm, cm, or inches).
3. Enter the bar length and choose the unit (m, mm, ft, or inches).
4. Optionally enter a quantity to calculate total weight for multiple bars.
5. Click "Calculate Weight" — the tool applies W = (π/4) × D² × L × ρ and displays results in kg and lbs.
6. Use the Copy button to copy the result summary to your clipboard.
