How is lead metal weight calculated?

Weight is calculated by multiplying the stock piece’s volume (cross-sectional area multiplied by length) by the density of lead (nominally 11.34 g/cm³ or 708 lb/ft³).

Why is lead commonly used for ballast and shielding?

Lead has an exceptionally high density (11.34 g/cm³), making it effective for compact counterweights, marine ballast, acoustic dampening, and radiation shielding.

What density is used for lead?

The default density is 11.34 g/cm³, which is the density of pure lead (Pb). For common lead alloys, you can enter a custom value — for example, 11.0 g/cm³ for lead-antimony alloy, or 10.66 g/cm³ for 50/50 lead-tin solder.

What geometries are supported?

Three cross-section types are supported: solid cylinder (round bar or rod), hollow cylinder (lead pipe or tube), and rectangular bar (flat or square lead stock).

What units are supported?

Metric (mm for cross-section dimensions, m for length, output in kg) and imperial (inches for dimensions, feet for length, output in lb). Toggle at any time — inputs are not cleared when switching.

Does the density unit change in imperial mode?

No. The density input remains in g/cm³ in both modes; imperial mode converts dimensions and displays weight in pounds. Pure lead defaults to 11.34 g/cm³.
