## How to convert

1 meter per hour (m/h) = 0.000621371 mile per hour (mph). Meter Per Hour (m/h) is a unit of Speed used in Metric system. Mile Per Hour (mph) is a unit of Speed used in Standard system.

## Definition of Meters Per Hour

Meters per hour (m/h) is a unit of speed that measures how fast something is moving in terms of meters per unit of time. It is a metric unit that is derived from the base unit of length, the meter, and the base unit of time, the hour. It is rarely used however, as the units of meters per second and kilometers per hour are considered sufficient for most situations.

One meter per hour is equal to 0.00027777777777778 meters per second, or 0.001 kilometers per hour. It can also be converted to other units of speed, such as feet per second, miles per hour, or knots, by using appropriate conversion factors.

## How to Convert Meters Per Hour

To convert meters per hour to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert meters per hour to feet per second, we need to multiply by 0.0009113444153, since there are 0.0009113444153 feet in one meter. To convert meters per hour to kilometers per hour, we need to multiply by 0.001, since there are 0.001 kilometers in one meter.

Here are some examples of how to convert meters per hour to other units of length in the US Standard system and the SI system:

• To convert 10 m/h to feet per second (fps), we multiply by 0.0009113444153: 10 m/h x 0.0009113444153 = 0.009113444153 fps
• To convert 20 m/h to miles per hour (mph), we multiply by 0.0006213711922, since there are 0.0006213711922 miles in one meter: 20 m/h x 0.0006213711922 = 0.012427423844 mph
• To convert 30 m/h to knots (kn), we multiply by 0.0005399568035, since there are 0.0005399568035 nautical miles in one meter: 30 m/h x 0.0005399568035 = 0.016198704105 kn
• To convert 40 m/h to meters per second (m/s), we divide by 3600, since there are 3600 seconds in one hour: 40 m/h / 3600 = 0.011111111111 m/s
• To convert 50 m/h to meters per minute (m/min), we divide by 60, since there are 60 minutes in one hour: 50 m/h / 60 = 0.833333333333 m/min
• To convert 60 m/h to centimeters per second (cm/s), we multiply by 100, since there are 100 centimeters in one meter, and divide by 3600: 60 m/h x 100 / 3600 = 1.666666666667 cm/s

## Where Meters Per Hour Are Used

Meters per hour are mainly used for measuring very slow speeds or velocities of objects or phenomena that move in terms of meters per unit of time. They are often used in scientific fields such as geology, biology, astronomy, and physics, where the speed or velocity of an object or phenomenon is very small compared to the usual units of speed.

For example, a glacier may have a speed of a few meters per hour, which means that it moves a few meters in one hour. A snail may have a speed of up to 47 meters per hour, which means that it can travel up to 47 meters in one hour. A planet may have an orbital velocity of thousands of meters per hour, which means that it covers thousands of meters along its orbit in one hour.

Meters per hour are also used in some other fields where the speed or velocity of an object or phenomenon is measured in terms of meters per unit of time.

## History of Meters Per Hour

The origin of meters per hour as a unit of speed can be traced back to the development of the metric system and the meter as a unit of length in the late eighteenth century. The meter was defined as one ten-millionth of the distance from the equator to the North Pole along a meridian through Paris.

The term meter first appeared in English in 1797, but it was not until later in the early nineteenth century that the use of meters per hour became more common; before that, other units such as feet per hour or leagues per hour were preferred for expressing speed.

Meters per hour have been used ever since as a standard unit of speed for measuring very slow speeds or velocities of objects or phenomena that move in terms of meters per unit of time. They have also been adopted by some international organizations and conventions, such as the International System of Units and the International Astronomical Union.

• To convert 600 m/h to centimeters per second, we multiply by 100 and divide by 3600: 600 m/h x 100 / 3600 = 16.66666666667 cm/s
• To convert 700 m/h to millimeters per minute, we multiply by 1000, since there are 1000 millimeters in one meter, and divide by 60: 700 m/h x 1000 / 60 = 11666.666666667 mm/min
Meters per hour also can be marked as m/h and metres per hour (alternative British English spelling in UK).

## Definition of Miles Per Hour

Miles per hour (mph, m.p.h., MPH, or mi/h) is a unit of speed that measures how fast something is moving in terms of miles per unit of time. It is commonly used in the United States, the United Kingdom, and some other countries that use the US Standard system of measurement or have close historical ties with them. The speed limit signs on roads and highways are usually expressed in mph.

One mile per hour is equal to 1.609344 kilometers per hour, or 0.44704 meters per second. It can also be converted to other units of speed, such as feet per second, knots, or meters per second, by using appropriate conversion factors.

## Where Miles Per Hour Are Used

Miles per hour are mainly used in the United States, the United Kingdom, and some other countries that use the US Standard system of measurement or have close historical ties with them. They are often used for car speeds and road signs, as well as for trains, planes, boats, and bicycles.

For example, a car may have a speed of 60 mph, which means that it travels a distance of 60 miles in one hour. A road sign may indicate a speed limit of 55 mph, which means that drivers should not exceed this speed on that road section. A train may have a speed of up to 150 mph, which means that it covers a distance of up to 150 miles in one hour.

Miles per hour are also used in some other fields, such as sports, weather, and astronomy, where the speed or velocity of an object or phenomenon is measured in miles per unit of time.

## History of Miles Per Hour

The origin of miles per hour as a unit of speed can be traced back to the development of the US Standard system and the mile as a unit of length in the late eighteenth century. The mile was defined as one thousand six hundred and nine meters (or eight furlongs) based on the English statute mile.

The term mile first appeared in English in the late fourteenth century, but it was not until later in the early nineteenth century that the use of miles per hour became more common; before that, other units such as feet per second or leagues per hour were preferred for expressing speed.

Miles per hour have been used ever since as a standard unit of speed for the United States, the United Kingdom, and some other countries that use the US Standard system or have close historical ties with them. They have also been adopted by some international organizations and conventions, such as the International Civil Aviation Organization and the International System of Units.
