Metal Calculators

Metal weight calculator

Calculate metal weight with confidence.

Choose a material and stock form, enter the dimensions, and get a theoretical weight you can check and share.

  • Metric and imperial units
  • Material-specific density
  • Formula and assumptions kept in view

How calculations work
  1. FormulaFind the cross-sectional area and volume for the selected shape.
  2. DensityApply the documented density for the material or alloy.
  3. UnitsConvert consistently, then show the theoretical weight at useful precision.

Check the basis

Know what supports the result

Formula references, material-density sources, and checked dates are available so you can verify the assumptions behind an estimate.
