Calculate MIL Thickness

Product Rate-Of-Use Information

All Coatings are normally measured and calculated in "Mil Thickness", (thousands of an inch)

Formulas For Calculating Coatings Consumption (This must assume that the surface to be coated is flat and smooth)

There are 1,604 sq. ft., 1 mil thick, in a US gallon of any liquid.

1,604 divided by mil thickness (desired)=sq.ft. Coverage

1,604 divided by sq. ft. Coverage (desired)=mil thickness

Use these formulas to calculate any coating project, or use our ready reference charts below for calculating paint coverage
