How to Convert Kilometers to Micrometers
To convert a measurement in kilometers to a measurement in micrometers, multiply 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:
micrometers = kilometers × 1,000,000,000
The length in micrometers is equal to the length in kilometers multiplied by 1,000,000,000.
How Many Micrometers Are in a Kilometer?
There are 1,000,000,000 micrometers in a kilometer, which is why we use this value in the formula above.
1 km = 1,000,000,000 µm
Kilometers and micrometers are both units used to measure length. Keep reading to learn more about each unit of measure.
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.

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.
