Resin Weight Calculator

Convert between the volume and the weight of a resin mix at a density you choose, in millilitres, litres, grams and kilograms.

Resin & Epoxy

Resin is sold by weight and poured by volume, so the same batch has two numbers and the conversion between them depends on density. This calculator converts in either direction and shows the working in litres, millilitres, kilograms and grams. It is a planning estimate, and the density of your own product comes from its technical data sheet rather than from a default.

Frequently asked questions

How much does 100 ml of resin weigh?

About 110 grams at the usual density of 1.1 grams per millilitre, and between 105 and 120 grams across the range most epoxy products occupy. The exact figure is on your product's technical data sheet, and a filled or heavily pigmented mix is at the top of that range or above it. Measuring a small sample on a scale settles it for your own materials.

How do I convert grams of resin to millilitres?

Divide the weight by the density. Two hundred and twenty grams at 1.1 grams per millilitre is 200 millilitres. If you only know the density in pounds per gallon, convert it first: one gram per millilitre is about 8.35 pounds per US gallon, so a resin at 9.2 pounds per gallon is about 1.1 grams per millilitre.

Is one millilitre of resin the same as one gram?

No. Water is one gram per millilitre, but epoxy is denser than water, so a millilitre of resin weighs about 1.1 grams. That is why a 500 gram kit is smaller in volume than a 500 millilitre bottle, and it is the reason weighing a batch and measuring a batch give different numbers when the ratio is quoted the other way round.

Does a pigment change the weight of a batch?

Yes, and by more than most people expect if the pigment is a metal powder or a heavy mineral filler. Mica and alcohol based dyes add very little mass, while bronze powder, iron filings and stone fillers add a lot. The finished weight matters for a wall hung piece, a jewellery component or anything that ships, so weigh a small sample of the real mix if it does.
