How to convert microinches to nanometers
1 microinch is equal to 25.4 nanometers, and 1 nanometer is equal to 0.03937007874 microinches. To convert, multiply by the conversion factor:
nanometers = microinches × 25.4
nanometers = microinches ÷ 0.03937007874Example: convert 15 µin to nm: 15 × 25.4 = 381 nm.

About the microinch
A microinch is one millionth of an inch (25.4 nm). It's used to specify surface roughness in machining.
Symbol: µin · 1 µin = 2.54 × 10⁻⁸ m · Category: Imperial & US customary
About the nanometer
A nanometer is one billionth of a meter. It's used for wavelengths of light (visible light is about 380–750 nm), molecules and chip manufacturing processes.
Symbol: nm · 1 nm = 1 × 10⁻⁹ m · Category: Metric (SI)
