Examples
1
A race car drives at a speed of 150 miles per hour during a race. Convert this speed from miles per hour to Kilometer/second.
Answer:
Given:
The speed in mile/hour is:
Speed(Mile/hour) = 150
Formula:
The formula to convert speed from mile/hour to kilometer/second is:
Substitute given weight Speed(Mile/hour) = 500 in the above formula.
Speed(Kilometer/second) = 500 / 2236.9362921
Speed(Kilometer/second) = 0.2235
Final Answer:
Therefore, 500 mi/h is equal to 0.2235 km/s.
The speed is 0.2235 km/s, in kilometer/second.

Mile/hour
The mile per hour (mph) is a unit of speed commonly used in the United States and the United Kingdom to measure the speed of vehicles. It indicates the number of miles traveled in one hour. This unit is prevalent in transportation and is used on road signs and vehicle speedometers in countries where the imperial system is used.
Kilometer/second
The kilometer per second (km/s) is a unit of speed that represents how many kilometers an object travels in one second. This unit is often used in astronomy and space science to describe the velocities of celestial bodies and spacecraft, as these speeds are far beyond those encountered in everyday life.
