Meters per second to miles per hour

1 meter per second = 2.23694 miles per hour

Type a value in meters per second (m/s) to get miles per hour (mph) straight away. A meter per second is larger than a mile per hour, so the number goes up. Both units belong to speed, measured here against the meter per second.

1 m/s = 2.2369363 mph

Formula

mph = m/s × 2.2369363

One meter per second is 2.2369363 miles per hour, so multiply the meter per second value by that factor. Here m/s is the value in meters per second and mph is the result in miles per hour.

Worked example: 10 meters per second × 2.2369363 = 22.3694 miles per hour.
