Mix Ratio Calculator

Many materials, especially epoxy and tin-cure silicone, require a mix ratio by either weight or volume other than 1:1. Use this page to help determine how much of each material you will need to mix.

Fill in the mix ratio according to the instructions on the material you're using. For example, Smooth-on's EpoxAcoat is 5A:1B by volume (measured using measuring cups), or 100A:15B by weight (measured using an accurate scale, preferably digital).
