Conversion Definitions
The following is a list of definitions relating to conversions between kilometers per second and miles per second.
What is kilometers per second (km/s)?
Kilometers per second is a unit of Speed or Velocity in the Metric System. It measures the number of kilometers traveled in a second. The symbol for kilometers per second is km/s and the International spelling for this unit is kilometres per second. There are 1.609344 km/s in mi/s.
What is miles per second (mi/s)?
Miles per second is a unit of Speed or Velocity in both US Customary Units as well as the Imperial System. It measures the number of miles traveled in a second. The symbol for miles per second is mi/s. There are 0.6213711922 mi/s in km/s.
Conversion Formula
Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.
The formula to convert from km/s to mi/s is:
mi/s = km/s ÷ 1.609344
Conversion Example
Next, let's look at an example showing the work and calculations that are involved in converting from kilometers per second to miles per second (km/s to mi/s).
Kilometers per second to Miles per second Conversion Example
Task: Convert 2,500 kilometers per second to miles per second (show work) Formula: km/s ÷ 1.609344 = mi/s Calculations: 2,500 km/s ÷ 1.609344 = 1,553.4279805933 mi/s Result: 2,500 km/s is equal to 1,553.4279805933 mi/s
