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:
kilometers = micrometers ÷ 1,000,000,000
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.
kilometers = (5,000,000,000 µm ÷ 1,000,000,000) = 5 km
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 103. Kilometers can be abbreviated as km; for example, 1 kilometer can be written as 1 km.
