The calculation for determining the amount of epoxy you need is a simple volume calculation. You simply multiple the length of the pour by the depth of the pour by the average width of the pour and then convert to liters. When calculating the average width of the pour, we measure the width every 6 inches along the entire work piece and then divide by the total number of width measurements you took to determine our average.

Length (L) X Depth (D) by Average Width (AVG W)

Example:

Length: 48”

Depth 1.5”

Average Width: 6”

48” x 1.5” x 6” = 432 cubic inches

432 cubic inches = 7.08 Litres (converted using google: Type “432 cubic inches to litres” in to the search bar)

You can also divide the cubic inches by 61 to determine the total number of litres needed.

432 / 61 =  7.08 Litres
