Select the shape and material (lead by default), then enter the required variables. The calculator will evaluate and display the total weight.
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 = π * D^2/4 * L * d
Lead Square Hollow Tube Weight Formula = [W^2 - (W - 2T)^2] * L * d
Lead Round Hollow Tube Weight Formula = π * (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 all length inputs to inches and all density inputs to lb/in³ internally. You can enter lengths in inches, feet, centimeters, millimeters, or meters and choose density in lb/in³, kg/m³, or g/cm³—unit conversions are handled automatically. If you calculate manually, make sure your volume and density units are consistent.
What is the density of Lead?
The density of pure lead at room temperature (about 20 °C) is approximately 0.4097 lb/in³ (11.34 g/cm³).
