(π * r2 * h) is the volume formula for a round fire pit

(π * r2 * h) ÷ 22.5 in.3

22.5 = cubic inches per pound of FireCrystals

Weight is 10.5 pounds per gallon

Calculations are amounts we suggest for a 3 inch thickness in the fireplace to achieve the proper thermal dynamic efficiency, which we have proven over the last seven years of test burning.
