Convert micrometer to kilometer
Please provide values below to convert micrometer [µm] to kilometer [km], or Convert kilometer to micrometer.
1 µm = 1.0000e-09 km. To convert micrometer to kilometer, multiply the value by 1.0000e-09; to go the other way, divide by it (1 km = 1000000000 µm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 µm = 1.0000e-09 km
- 1 km = 1000000000 µm
- 10 µm = 1e-08 km
- 100 µm = 1e-07 km
How to Convert Micrometer to Kilometer
1 µm = 1e-09 km
Example: convert 15 µm to km:
15 µm = 15 × 1e-09 km = 1.5e-08 km

Micrometer
A micrometer, also known as a micron, is a unit of length equal to one-millionth of a meter.
History/Origin
The term "micron" and the symbol µ were officially declared obsolete by the General Conference on Weights and Measures (CGPM) in 1967, and "micrometer" became the official term.
Current Use
The micrometer is a common unit for measuring the wavelength of infrared radiation, as well as the size of biological cells and bacteria. It is also widely used in technology and engineering.
Kilometer
A kilometer is a unit of length in the metric system, equal to one thousand meters.
History/Origin
The term "kilometer" is derived from the Greek words "khilioi" (thousand) and "metron" (measure). The kilometer was first defined as part of the metric system in France in 1795.
Current Use
The kilometer is the most widely used unit of distance for road signs and travel distances in the world, with the notable exceptions of the United States and the United Kingdom.
Frequently Asked Questions
What is 1 micrometer in kilometer?
1 micrometer (µm) = 1.0000e-09 kilometer (km).
How do you convert micrometer to kilometer?
Multiply the micrometer value by 1.0000e-09. For example, 25 µm × 1.0000e-09 = 2.5e-08 km.
What is 10 micrometer in kilometer?
10 µm = 1e-08 km.
Which unit is larger, the micrometer or the kilometer?
The kilometer is the larger unit: 1 µm equals only 1.0000e-09 km.
