## How to Convert Micrometers to Inches

To convert a measurement in micrometers to a measurement in inches, divide the length by the following conversion ratio: 25,400 micrometers/inch.

Since one inch is equal to 25,400 micrometers, you can use this simple formula to convert:

The length in inches is equal to the length in 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.

## What is a Micrometer?

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 millionths, or 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.

## What is an Inch?

An inch is a unit of length 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 known as a double-prime.
Often a double-quote (") is used instead of a double-prime for convenience.
A double-prime is commonly used to express *1 in* as 1″.

The standard ruler is 12 inches long and is a common tool for measuring a length in inches. Another frequently used tool to perform measurements in inches is a tape measure, which commonly comes in lengths from 6' - 35'. Other types of devices used to make measurements in inches 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 a combination of both values, so make sure you get the correct type for your needs.
