Weight Chart for Non-Living Substances

Note:

The weights given in these tables are necessarily approximate; variation within a class of substance can be large. I have taken an average weight per cubic metre for a given substance and rounded it to the nearest 25 kilograms. The exception is the Metals table, since there is seldom much variation in weight between different batches of the same metal I have given the weight per cubic metre reasonably accurately.

Weights in lbs/ft³ have been calculated at 1/16 kg/m³ and rounded out to the nearest pound, which should be accurate enough for roleplaying purposes.

Of course, the chances of ever having to calculate the weight of something like diamond in anything like cubic feet or metres are vanishingly small, but you just never know.........

If you feel the need for great accuracy in your metal object weight calculations, Shane at machinetoolshub.com has provided a couple of useful pages:

• https://machinetoolshub.com/metal-density-table/ gives accurate metal density for a long list of metals and alloys
• https://machinetoolshub.com/calculator/metal-weight-calculator/ provides weight calculations for a variety of metal shapes, once you know the appropriate metal density.
