About this tool

Estimates raw stock weight from a shape, dimensions, and material density.

Inputs
  • Shape (rectangular, round bar, tube)
  • Dimensions in inches or millimetres
  • Material
Assumptions
  • Nominal densities at room temperature
  • Solid, uniform stock — no holes, chamfers, or mill scale allowance
  • Nominal, not actual, stock dimensions
Sources
  • Published material density tables (ASM, MatWeb)
Valid range
  • Any positive dimensions; tube inner diameter must be less than outer diameter.
Limitations
  • Alloy and temper variation can shift density by 1–3%
  • Does not include the saw-cut kerf or stock oversize you'd actually order

Values are starting points for planning — verify against your tooling and machine documentation before cutting. Report an issue with this tool →
