## 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:

inches = micrometers ÷ 25,400

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.
50,000 µm = (50,000 ÷ 25,400) = 1.968504"

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

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.

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.
