Donaldson R F Metal Weight & Density Calculator
How much a volume of metal weighs, or how much volume a given weight takes up.
How this is worked out
Density links weight and volume: weight = volume × density, so this tool just rearranges that for whichever one you don't have. Density varies by alloy and manufacturing process even within one metal (a bronze can be 8% tin or 14%, for instance), so the figures here are reference points, not exact values for a specific batch of material — for precise engineering work, use your supplier's own certified density.
Frequently asked questions
Why do bronze and stainless steel show a range?
Because "bronze" and "stainless steel" each cover a family of alloys with somewhat different compositions and densities, rather than one fixed material — this tool uses the midpoint of the commonly-quoted range, shown alongside the result.
How much does a cubic metre of gold weigh?
About 19.3 tonnes — gold is roughly 2.4 times denser than lead and over 7 times denser than aluminium, which is part of why a surprisingly small bar or coin can be so heavy.
