How many miles per hour is a kilometer per hour?

A kilometer per hour is slower than a mile per hour. 0.621 miles per hour is the same velocity as one kilometer per hour. A kilometer per hour is 62.14% the velocity a mile per hour. An object moving at a mile per hour is 60.93% faster than an object traveling at one kilometer per hour.

Kilometers per hour to miles per hour conversion factor and formulas

The conversion factor between kilometers per hour and miles per hour is 1.609. This represents the ratio of kilometers per hour per one mile per hour. To calculate the value in miles per hour, we can either divide by the conversion factor or multiply by its inverse.

Division

To convert from kilometers per hour to miles per hour, divide kilometers per hour by 1.609.
The formula is expressed as:
km/h ÷ 1.609 = mph

Multiplication

Alternatively we can multiply by the inverse conversion factor to get the same result.
The inverse of 1.609 is 1/1.609 or 0.621. To convert from kilometers per hour to miles per hour, multiply kilometers per hour by 0.621.
The formula is expressed as:
km/h × 0.621 = mph

To convert 244 kilometers per hour to miles per hour, divide 244 kilometers per hour by 1.609.
244 km/h ÷ 1.609 = 151.615 mph

About this conversion

Converting kilometers per hour to miles per hour is a conversion between units from separate unit systems - kilometers per hour are metric (SI) defined units while miles per hour are US Customary / UK Imperial .

About Kilometers per hour

Within the SI (metric) system of measurement, a kilometer per hour (km/h) is the distance traveled in one hour as measured in kilometers (1,000 meters). It is commonly used as measurement of velocity over geographic distances. Kilometers per hour are commonly used to measure vehicle speed and speed limits. The official SI symbol is km/h, however kph and km/hr are also used.

About Miles per hour

Miles per hour is a velocity measurement within the US/UK Imperial systems. It is defined as the number of miles traveled in one hour. MPH is frequently used for measurement and regulation of vehicle speed limits in the US, UK and many British dependencies. The common symbols for miles per hour are mph, MPH or mi/hr.
