Conversion Definitions
The following is a list of definitions relating to conversions between feet per second and kilometers per second.
What is feet per second (ft/s)?
Feet 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 feet traveled in a second. The symbol for feet per second is ft/s. There are 3,280.8398950131 ft/s in km/s.
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 0.0003048 km/s in ft/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 ft/s to km/s is:
km/s = ft/s x 0.0003048
Conversion Example
Next, let's look at an example showing the work and calculations that are involved in converting from feet per second to kilometers per second (ft/s to km/s).
Feet per second to Kilometers per second Conversion Example
Task: Convert 2,500 feet per second to kilometers per second (show work) Formula: ft/s x 0.0003048 = km/s Calculations: 2,500 ft/s x 0.0003048 = 0.762 km/s Result: 2,500 ft/s is equal to 0.762 km/s
