Microns to inches conversion factor and formulas

Formula

The conversion factor between microns and inches is 25,400. This represents the ratio of microns per one inch. To calculate the value in inches, we can either divide by the conversion factor or multiply by its inverse.

Division

To convert from microns to inches, divide microns by 25,400.
The formula is expressed as:
µ ÷ 25,400 = in

Multiplication

Alternatively we can multiply by the inverse conversion factor to get the same result.
The inverse of 25,400 is 1/25,400 or 0. To convert from microns to inches, multiply microns by 0.
The formula is expressed as:
µ × 0 = in

About this conversion

Converting microns to inches is a conversion between units from separate unit systems - microns are metric (SI) defined units while inches are US Customary / UK Imperial .

About Microns

SI Unit

The micrometer is a very small unit of length within the SI (metric) system. It is officially defined as one millionth (1/1,000,000) of a meter or one thousandth (1/1,000) of a millimeter. The micrometer is also commonly referred to as a micron. It is commonly used when measuring microscopic sizes like bacteria or biological cells. Internationally it is spelled 'micrometre' whereas the U.S. spells it 'micrometer'. The symbol for a micrometer is µ.

About Inches

Customary/Imperial Unit

The inch is a length measurement within US Customary and British Imperial units of measure. It is officially defined as 25.4 millimeters. Twelve inches equal one foot and thirty six inches equal a yard in the US/Imperial systems. The abbreviation for inches is either in or " as in 12". When measuring in inches, it is common to subdivide the inch into fractional portions like a half-inch, quarter-inch, eighth of an inch etc. instead of using decimals. Inches are frequently used in the building construction trades in the US and Canada. Internationally, inches are a common measurement of tire size and display screen sizes. Historically the inch is derived from the width of an adult thumb.
