In the United States, the most widely used expression for quantitatively defining the rate of corrosion in mils per year (abbreviated MPY or mils/yr) and it is calculated from the following formula:

Mils per year = 534 * W / d * A * T

where

  • W is the weight loss in milligram;
  • d is the density, g/cm3
  • A is specimen area, inch2
  • T is the exposure time, hour
