Online calculators to convert meters per second to kilometers per second (m/s to km/s) and kilometers per second to meters per second (km/s to m/s) with additional formulas, examples, and conversion tables. Our conversions provide a quick and easy way to convert between these units.

Enter your value in one of the conversion calculators below to **convert m/s to km/s ** or **convert km/s to m/s**.

Let's take a closer look at the conversion formulas so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.

The formula to convert from m/s to km/s is:

km/s = m/s x 0.001

The formula to convert from km/s to m/s is:

m/s = km/s x 1,000

Next, let's look at some examples showing the work and calculations that are involved in converting between meters per second (m/s) and kilometers per second (km/s).

Task: Convert 450 m/s to km/s (show work)Formula:m/s x 0.001 = km/sCalculations:450 m/s x 0.001 = 0.45 km/sResult:450 m/s is equal to 0.45 km/s

Task: Convert 35 km/s to m/s (show work)Formula:km/s x 1,000 = m/sCalculations:35 km/s x 1,000 = 35,000 m/sResult:35 km/s is equal to 35,000 m/s

For quick reference purposes, below are conversion tables that you can use to convert from m/s to km/s, and km/s to m/s.
