## How to Convert Micrometers to Inches

To convert a micrometer measurement to an inch measurement, divide the length by the conversion ratio. One inch is equal to 25,400 micrometers, so use this simple formula to convert:

The length in inches is equal to the micrometers divided by 25,400.

**For example,**here's how to convert 50,000 micrometers to inches using the formula above.

Our inch fraction calculator can add micrometers and inches together and it also automatically converts the results to US customary, imperial and SI metric values.

Micrometers and inches are both units used to measure length. Keep reading to learn more about each unit of measure.

## Micrometers

One micrometer is equal to one-millionth (1/1,000,000) of a meter, which is defined as the distance light travels in a vacuum in a ^{1}/_{299,792,458} second time interval.

The micrometer, or micrometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "micro" is the prefix for 10^{-6}. A micrometer is sometimes also referred to as a micron. Micrometers can be abbreviated as *µm*, for example 1 micrometer can be written as 1 µm.

To get an idea of the actual physical length of a micrometer, one human hair is 40-50 µm thick, demonstrating how small this unit of measure is.

## Inches

An inch is a unit of linear length measure equal to ^{1}/_{12} of a foot or ^{1}/_{36} of a yard.
Because the international yard is legally defined to be equal to exactly 0.9144 meters, one inch is equal to 2.54 centimeters.^{[1]}

The inch is a US customary and imperial unit of length. Inches can be abbreviated as *in*, for example 1 inch can be written as 1 in.

Inches can also be denoted using the *″* symbol, otherwise know as a double-prime.
Often a double-quote (") is used instead of a double-prime for convenience.
Using the double-prime, *1 in* can be written as 1″.

The standard ruler has 12", and are a common measuring tool for measuring inches. They are also often measured using tape measures which commonly come in lengths from 6' - 35'. Other types of measuring devices include scales, calipers, measuring wheels, micrometers, yardsticks, and even lasers.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or combination with both values, so make sure you get the correct type for your needs.

If you need a ruler you can also download and print our free printable rulers, which include both imperial and metric measurements.
