Convert Micrometer to Kilometer
Enter the number of micrometers that you want to convert to kilometers.
How to Convert Micrometers to Kilometers
The micrometer and kilometer are both units of length. By definition, 1 kilometer equals exactly 1000000000 micrometers. This means to convert micrometers to kilometers, you divide by 1000000000.
Formula
Step-by-Step Example
Convert 5 μm to kilometers:
We need to convert micrometers to kilometers
Since 1 km = 1000000000 μm, divide by 1000000000
5 ÷ 1000000000 = 5e-9
5 μm = 5e-9 km

About These Units
Micrometer (μm)
A micrometer (μm), also called a micron, is a metric unit equal to one millionth of a meter or 0.001 millimeters. Micrometers are used for measuring bacteria (1-10 μm), human hair diameter (70-100 μm), red blood cells (7 μm), and semiconductor features.
Kilometer (km)
A kilometer (km) is a metric unit of length equal to 1,000 meters or approximately 0.621 miles. Kilometers are the standard unit for measuring road distances, running races, and geographic distances in most countries worldwide. Common conversions: 1 km = 0.621 miles, 1 mile = 1.609 km.
