The conversion formula for metres per second (m/s) to miles per hour (mi/h, mph, miph) conversions is as follows:
The conversion formula for kilometres per hour (km/h, kph, kmph) to metres per second (m/s) conversions is as follows:
The first formula is correct to six decimal places, the exact value being 1/0.44704.
The conversion from metres per second to miles per hour can be thought of in two steps:
1. Convert metres per second to metres per hour by multiplying by 3,600, the number of seconds in an hour.
2. Convert metres per hour to miles per hour by dividing by 1,609.344, the number of metres in a mile.
The metre per second is the main SI derived unit for both speed and velocity. It is used for most scientific work, outside of astronomy but isn't used on a daily basis for car speeds and road speed limits.
One metre per second is the speed when travelling one metre distance in one second time.
metre and second
The metre per second is derived from the SI base units of distance and time.
Formal: m s-1
Alternate abbreviations include m·s-1, m/s and mps.
The metre per second is one of the simplest SI units being derived from the distance unit of metres and the time unit of seconds.
Metres per second are recognised world wide although they are not often used outside of scientific applications in the United States.
Miles per hour are the main unit of speed used in the United States, United Kingdom and other countries that use imperial or US customary measurements for road signs and speedometers.
Imperial & US Customary
The mile per hour is defined as the speed when travelling a distance of one mile in a time of one hour.
yard and second
Miles per hour is a derived unit based upon units of distance (mile) and time (hour). Each of these units is defined in terms of other units, the mile being defined as 1760 yards and the hour being defined as 3,600 seconds.
The most common abbreviation for miles per hour is mph, with other abbreviations including m.p.h., MPH, M.P.H, m/h, m/hr and mi/hr.
Miles per hour came into common useage during the 18th century with the running of regular stage coaches in the United Kingdom (This link shows an 1825 document specifying a speed of 20mph for waggon post). After this the unit became the de facto standard for speed of locomotives on the railways in countries using imperial or US customary units.
Despite the now almost universal adoption of the metric system, a few countries (again those influenced by the UK and the US) still use miles per hour as their standard for road speed limits.
Miles per hour are used in countries that have not yet fully adopted the metric system, including the United States, United Kingdom, Belize, Liberia and Myanmar.
