Kilometers to micrometers
1 kilometer in micrometers
1 km = 1,000,000,000 µm
µm = km × 1,000,000,000
To convert kilometers to micrometers, multiply by 1,000,000,000. 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 µm = km × 1,000,000,000. Both units measure length, so the conversion is a fixed factor that never changes.
Common questions
- How many micrometers are in one kilometer?
- One kilometer equals 1,000,000,000 micrometers. µm = km × 1,000,000,000.
- How do you convert kilometers to micrometers?
- Use µm = km × 1,000,000,000. So 10 km is 10,000,000,000 µm.
- How many kilometers are in one micrometer?
- One micrometer equals 1 × 10^-9 kilometers, which is the reverse of the conversion above.
