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 = Microinc
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 = Required Stock Removal
Example: Existing Finish = 1.25 μm"; Desired Finish = 0.25 μm", (1.25 - 0.25) / 100 = 0.01mm

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

Formulas for determining minimum stock removal required on diameter to achieve desired surface finish.

Surface Finish in Microinches - (μ") Ra
( Existing Finish - Desired Finish ) / 100,000 = Required Stock Removal
Example : Existing Finish = 50 μm"; Desired Finish = 10 μm", (50 - 10) / 100,000 = 0.0004inch
