Conversion Definitions
The following is a list of definitions relating to conversions between miles per hour and decimeters per second.
What is miles per hour (mph)?
Miles 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 miles traveled in an hour. The symbol for miles per hour is mph. There are 0.2236936292 mph in dm/s.
What is decimeters per second (dm/s)?
Decimeters per second is a unit of Speed or Velocity in the Metric System. It measures the number of decimeters traveled in a second. The symbol for decimeters per second is dm/s and the International spelling for this unit is decimetres per second. There are 4.4704 dm/s in mph.
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 mph to dm/s is:
dm/s = mph x 4.4704
