Measure or weigh
Use the box or round options for simple shapes. For anything detailed, fill a cavity with water and weigh it, it is the most accurate way.
Tools and calculators

Work out how much wax, soap or resin fills each cavity.

Densities are typical figures. Check the one on your supplier's data sheet, and weigh a test pour before a big batch.

Getting the most from it.
Pick your material
Wax is lighter than water, resin and soap a little heavier, and concrete more than twice as heavy. That changes how much you need to buy.
Add a little extra
Jugs, spills and top-ups all use material. Ten per cent is a sensible cushion for most small-batch pours.
