Calculate lead weight for blocks, sheets, round bars, spheres, tubes, or known volumes in metric or imperial units, with kilograms and pounds.
Lead Weight Formulas
The following formulas are used to calculate the weight of lead in different shapes.
Lead Flat Sheet Weight Formula = L * W * T * d
Lead Round Bar Weight Formula = ฯ * D^2/4 * L * d
Lead Square Hollow Tube Weight Formula = [W^2 – (W – 2T)^2] * L * d
Lead Round Hollow Tube Weight Formula = ฯ * (R^2 – r^2) * L * d
Lead Square Angle Weight Formula = T * (A + B – T) * L * d
Lead T Bar Weight Formula = (Wf * Tf + Tw * (H – Tf)) * L * d
Lead C Channel Weight Formula = [Tw * (H – 2Tf) + 2 * W * Tf] * L * d
Variables used in these equations:
- L is the length
- W is the width (or outside width/flange width, depending on the shape)
- H is the overall height
- T is the thickness (sheet thickness, wall thickness, or angle thickness, depending on the shape)
- d is the density
- D is the diameter
- R is the outer radius
- r is the inner radius
- A is angle leg A
- B is angle leg B
- Wf is the T-bar flange width
- Tf is the flange thickness (T bar or C channel)
- Tw is the web thickness (T bar or C channel)
The calculator converts each dimension to centimeters and uses density in g/cmยณ. It supports blocks or sheets, round bars, spheres, round tubes, known volume, and reverse-solving solid volume from weight. Quantity applies to identical pieces. The other cross-section formulas above can be used separately with consistent volume and density units.
What is the density of lead?
The density of pure lead at room temperature (about 20 ยฐC) is approximately 0.4097 lb/inยณ (11.34 g/cmยณ).
