Micrometers to kilometers

1 micrometer in kilometers
1 µm = 1 × 10^-9 km
km = µm × 1 × 10^-9

To convert micrometers to kilometers, multiply by 1 × 10^-9. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works

The relationship is km = µm × 1 × 10^-9. Both units measure length, so the conversion is a fixed factor that never changes.

Common questions

How many kilometers are in one micrometer?
One micrometer equals 1 × 10^-9 kilometers. km = µm × 1 × 10^-9.
How do you convert micrometers to kilometers?
Use km = µm × 1 × 10^-9. So 10 µm is 1 × 10^-8 km.
How many micrometers are in one kilometer?
One kilometer equals 1,000,000,000 micrometers, which is the reverse of the conversion above.
