Epoxy mix ratio calculator (weight & volume)

Split two-component epoxy or paint kits by weight or volume, convert weight ratios with densities, and see Part A/B amounts instantly with a shareable URL.

Sample values are preloaded and calculated in your browser only; no data is sent.

How to use (3 steps)

  1. Pick metric or US units and choose whether the product ratio is by weight or volume.
  2. Enter the mix ratio and either the total amount, a known A/B amount, or densities to convert weight to volume.
  3. Review the auto-calculated amounts, copy the shareable URL, and mix thoroughly.

A 4:1 sample is preloaded so results appear right away.

FAQ

Should I mix by weight or by volume?

Follow the datasheet. If only a weight ratio is provided, measure by weight. Use the converter only when you must measure by volume.

How much deviation is acceptable?

Stay within the tolerance from the manufacturer—commonly within about ±2–3%. If you overshoot, remix a fresh batch instead of trying to fix a small cup.
