## What is the Formula to convert Mile/hour to Kilometer/second?

The formula to convert given speed from Mile/hour to Kilometer/second is:

Speed_{(Kilometer/second)} = Speed_{(Mile/hour)} / 2236.9362921

Substitute the given value of speed in mile/hour, i.e., Speed_{(Mile/hour)} in the above formula and simplify the right-hand side value. The resulting value is the speed in kilometer/second, i.e., Speed_{(Kilometer/second)}.

## Calculation

## Examples

### 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:

Speed_{(Kilometer/second)} = Speed_{(Mile/hour)} / 2236.9362921

**Substitution:**

Substitute given weight **Speed _{(Mile/hour)} = 150** in the above formula.

Speed_{(Kilometer/second)} = 150 / 2236.9362921

Speed_{(Kilometer/second)} = 0.067056

**Final Answer:**

Therefore, **150 mi/h** is equal to **0.067056 km/s**.

The speed is **0.067056 km/s**, in kilometer/second.

### A commercial airplane cruises at 500 miles per hour.

Convert this speed from miles per hour to Kilometer/second.

#### Answer:

**Given:**

The speed in mile/hour is:

Speed_{(Mile/hour)} = 500

**Formula:**

The formula to convert speed from mile/hour to kilometer/second is:

Speed_{(Kilometer/second)} = Speed_{(Mile/hour)} / 2236.9362921

**Substitution:**

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.
