How many Meters per second equal one Mile per hour?

To answer this, we need to perform a conversion on both the length dimension and the time dimension. Since a mile is defined as 1609.344 meters according to the international standards for units and there are 3600 second in one hour, after dividing 1609.344 by 3600 we get that 0.44704 meters per second equal one mile per hour. The symbol for mile is "mi", while the symbol for meter is "m". In some places in the UK and the US, however, you might see "m" used a symbol for miles, leading to confusions, especially for visitors from abroad. This leads to the inconsistency of labeling miles per hour with "mph" which should more appropiately refer to meters per hour.

Difference between Miles per hour and Meters per second

The first difference is that one of these units represents a distance covered in a second, while the other represents a distance covered in an hour. The other component of the speed unit, the distance units, also presents several differences. For one, the mile is a part of the imperial system of units, while the meter is the base unit of the metric system. The two units correspond to very different lengths, with the mile being many orders of magnitude larger, thus miles are usually used to measure large distances, while meters are used for more modest ones. E.g. you would measure the distance travelled by a car or plane in miles, while a short walk or sprint in meters.

In general, meters per second is the preferred unit of speed in engineering, physics and other fields of applied science. Miles per hour, on the other hand, have more of an everyday usage in countries like the United States and a few of the other countries which once comprised the British Empire.

How to convert Miles per hour to Meters per second

As with other units of speed, the conversion operation should cover both dimensions: length and time. To convert miles to meters, multiply the distance in miles by 1609.344 to get the distance in meters and then divide by 3600 to convert hours to seconds. Equivalently, multiply the value in mph by 0.44704 to get mps. Conversion of measurements in miles per hour to measurements in meters per second is usually done with a calculator, and is even easier with our online miles per hour to meters per second converter, which also has a one-click copy/paste button for your convenience.

Miles per hour to Meters per second conversion example

Sample task: convert 100 miles per hour to meters per second. Solution:

mph * 0.44704 = mps
100 mph * 0.4470 = 44.7040 mps
End result:
100 mph is equal to 44.7040 mps
