## What Is a Micrometer?

A micrometer is a unit used to measure length.

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.

## How Long 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.

## How to Convert Micrometers

To convert micrometers to another unit of length, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[1]

You can find the conversion factors for micrometers in the conversion table below.

Then, multiply the length measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

micrometers × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
