Do you want to convert miles per hour to kilometers per second?

## How to Convert Kilometers per Second to Miles per Hour

To convert a measurement in kilometers per second to a measurement in miles per hour, multiply the speed by the following conversion ratio: 2,236.936292 miles per hour/kilometer per second.

Since one kilometer per second is equal to 2,236.936292 miles per hour, you can use this simple formula to convert:

miles per hour = kilometers per second × 2,236.936292

The speed in miles per hour is equal to the speed in kilometers per second multiplied by 2,236.936292.

For example, here's how to convert 5 kilometers per second to miles per hour using the formula above.
miles per hour = (5 km/s × 2,236.936292) = 11,184.68146 mph

Kilometers per second and miles per hour are both units used to measure speed. Keep reading to learn more about each unit of measure.

## What Are Kilometers per Second?

Kilometers per second are a measurement of speed expressing the distance traveled in kilometers in one second.

The kilometer per second, or kilometre per second, is an SI unit of speed in the metric system. Kilometers per second can be abbreviated as km/s, and are also sometimes abbreviated as km/sec. For example, 1 kilometer per second can be written as 1 km/s or 1 km/sec.

In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units. For example, km/s is expressing a change in length or distance relative to a change in time.

Kilometers per second can be expressed using the formula:
vkm/s = dkm / tsec

The velocity in kilometers per second is equal to the distance in kilometers divided by time in seconds.

## What Are Miles per Hour?

Miles per hour are a measurement of speed expressing the distance traveled in miles in one hour.

The mile per hour is a US customary and imperial unit of speed. Miles per hour can be abbreviated as mph, and are also sometimes abbreviated as mi/h or MPH. For example, 1 mile per hour can be written as 1 mph, 1 mi/h, or 1 MPH.

Miles per hour can be expressed using the formula:
vmph = dmi / thr

The velocity in miles per hour is equal to the distance in miles divided by time in hours.
