How to convert kilometers per second to meters per second
m/s = km/s × 1,000Multiply the value in kilometers per second by 1,000. To go the other way, multiply by 0.001 (or divide by 1,000).
A kilometer per second is larger than a meter per second: one kilometer per second contains 1,000 meters per second.
Worked examples
- 1 kilometer per second1 km/s × 1,000 = 1,000 m/s
- 5 kilometers per second5 km/s × 1,000 = 5,000 m/s
- 10 kilometers per second10 km/s × 1,000 = 10,000 m/s
- 20 kilometers per second20 km/s × 1,000 = 20,000 m/s
- 100 kilometers per second100 km/s × 1,000 = 100,000 m/s

About the units
Kilometer per second (km/s)
The kilometer per second (km/s) is a unit of speed in the International System of Units (SI). One kilometer per second equals 1,000 meters per second (m/s).
Meter per second (m/s)
The SI unit of speed. A brisk walk is about 1.5 m/s; Usain Bolt’s peak speed was about 12.4 m/s.
Frequently asked questions
How many meters per second are in one kilometer per second?
There are 1,000 meters per second in one kilometer per second, and this value is exact by definition.
How do I convert kilometers per second to meters per second?
Multiply the number of kilometers per second by 1,000. For example, 10 km/s × 1,000 = 10,000 m/s.
How many kilometers per second are in one meter per second?
One meter per second equals 0.001 kilometers per second. That is the reverse factor, 1 ÷ 1,000.
What is 10 kilometers per second in meters per second?
10 km/s = 10,000 m/s.
Is this km/s to m/s converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
