Conversion Definitions
The following is a list of definitions relating to conversions between feet per hour and kilometers per second.
What is feet per hour (ft/h)?
Feet per hour 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 an hour. The symbol for feet per hour is ft/h. There are 11,811,023.62 ft/h 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 0.0000000847 km/s in ft/h.
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/h to km/s is:
km/s = ft/h ÷ 11,811,023.62
Conversion Example
Next, let's look at an example showing the work and calculations that are involved in converting from feet per hour to kilometers per second (ft/h to km/s).
Feet per hour to Kilometers per second Conversion Example
Task: Convert 250,000 feet per hour to kilometers per second (show work) Formula: ft/h ÷ 11,811,023.62 = km/s Calculations: 250,000 ft/h ÷ 11,811,023.62 = 0.0211666667 km/s Result: 250,000 ft/h is equal to 0.0211666667 km/s
