What density is used for lead?

This calculator uses 11,340 kg/m³, which is the standard density of commercially pure lead at room temperature.

Can I use inches for the dimensions?

Yes. Select "inches" from the unit selector and all three inputs are interpreted in inches. The result is still shown in both kg and lbs.

What if the inner diameter is zero?

An inner diameter of zero means a solid lead rod, which this calculator handles correctly — it simply uses the full circular cross-section.

How is the volume calculated?

Volume = π/4 × (OD² − ID²) × Length. The result is multiplied by lead density to give mass.

Does this account for lead alloys?

No. The calculator uses pure lead density. Lead alloys (e.g., lead-antimony, lead-tin) have slightly different densities; adjust manually if precision is critical.
