## How to Convert Micrometers to Kilometers

To convert a measurement in micrometers to a measurement in kilometers, divide the length by the following conversion ratio: 1,000,000,000 micrometers/kilometer.

Since one kilometer is equal to 1,000,000,000 micrometers, you can use this simple formula to convert:

The length in kilometers is equal to the length in micrometers divided by 1,000,000,000.

**For example,**here's how to convert 5,000,000,000 micrometers to kilometers using the formula above.

Micrometers and kilometers 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 a Kilometer?

One kilometer is equal to 1,000 meters, which are defined as the distance light travels in a vacuum in ^{1}/_{299,792,458} of a second.^{[1]} One kilometer is equal to 0.621371 miles.

The kilometer, or kilometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "kilo" is the prefix for thousands, or 10^{3}. Kilometers can be abbreviated as *km*; for example, 1 kilometer can be written as 1 km.
