Surface Finish Conversions: Millimeter to Inch – To convert one unit of measure to the other use the following formulas. Micrometer to microinch: Micrometer x 40 = Microinch

Formulas for determining minimum stock removal required on diameter to achieve desired surface finish. Surface Finish in Micrometers – (μm) Ra

EXISTING FINISH – DESIRED FINISH
100,000		 = REQUIRED

Example: Existing Finish = 50 μm”; Desired Finish = 10 μm”

Surface Finish Conversions: Inch to Millimeter – To convert one unit of measure to the other use the following formulas. Microinch to micrometer: Microinch ÷ 40 = Micrometer

*If two values are shown: the first number is for the small parts, honed on machines with one horsepower or less; the second number is for large parts, honed on machines with two or more horsepower
