## How to convert

1 mile per hour (mph) = 0.44704 meter per second (m/s). Mile Per Hour (mph) is a unit of Speed used in Standard system. Meter Per Second (m/s) is a unit of Speed used in Metric system.

## Miles Per Hour

## 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.

## How to Convert Miles Per Hour

To convert miles per hour to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert miles per hour to kilometers per hour, we need to multiply by 1.609344, since there are 1.609344 kilometers in one mile. To convert miles per hour to meters per second, we need to multiply by 0.44704, since there are 0.44704 meters in one mile.

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

- To convert 10 mph to kilometers per hour (km/h), we multiply by 1.609344: 10 mph x 1.609344 = 16.09344 km/h
- To convert 20 mph to feet per second (fps), we multiply by 1.466666667, since there are 1.466666667 feet in one mile: 20 mph x 1.466666667 = 29.33333334 fps
- To convert 30 mph to knots (kn), we multiply by 0.8689762421, since there are 0.8689762421 nautical miles in one mile: 30 mph x 0.8689762421 = 26.069287263 kn
- To convert 40 mph to meters per second (m/s), we multiply by 0.44704: 40 mph x 0.44704 = 17.8816 m/s
- To convert 50 mph to meters per minute (m/min), we multiply by 26.8224, since there are 26.8224 minutes in one hour: 50 mph x 26.8224 = 1341.12 m/min
- To convert 60 mph to centimeters per second (cm/s), we multiply by 100, since there are 100 centimeters in one meter, and multiply by 0.44704: 60 mph x 100 x 0.44704 = 2682 cm/s

## 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.

## Example Conversions of Miles Per Hour to Other Units

Here are some examples of how to convert miles per hour to other units of speed, using the conversion factors given above:

- To convert 100 mph to kilometers per hour, we multiply by 1.609344: 100 mph x 1.609344 = 160.9344 km/h
- To convert 200 mph to feet per second, we multiply by 1.466666667: 200 mph x 1.466666667 = 293.3333334 fps
- To convert 300 mph to knots, we multiply by 0.8689762421: 300 mph x 0.8689762421 = 260.69287263 kn
- To convert 400 mph to meters per second, we multiply by 0.44704: 400 mph x 0.44704 = 178.816 m/s
- To convert 500 mph to meters per minute, we multiply by 26.8224: 500 mph x 26.8224 = 13411.2 m/min
- To convert 600 mph to centimeters per second, we multiply by 100 and multiply by 0.44704: 600 mph x 100 x 0.44704 = 268200 cm/s
- To convert 700 mph to millimeters per minute, we multiply by 1000, since there are 1000 millimeters in one meter, and multiply by 26.8224: 700 mph x 1000 x 26.8224 = 18774880 mm/min

## Meters per second: A unit of speed

Meters per second (m/s) is a unit of speed or velocity in the International System of Units (SI). It measures how fast an object is moving by calculating the distance traveled in meters divided by the time taken in seconds. For example, if a car travels 100 meters in 5 seconds, its speed is 20 m/s.

## How to convert meters per second

Meters per second can be converted to other units of speed or velocity by using simple conversion factors. Here are some common units and their conversion factors:

- Kilometers per hour (km/h): To convert from m/s to km/h, multiply by 3.6. To convert from km/h to m/s, divide by 3.6. For example, 20 m/s is equal to 72 km/h, and 50 km/h is equal to 13.89 m/s.
- Miles per hour (mph): To convert from m/s to mph, multiply by 2.2369. To convert from mph to m/s, divide by 2.2369. For example, 20 m/s is equal to 44.74 mph, and 30 mph is equal to 13.41 m/s.
- Knots (kn): To convert from m/s to kn, multiply by 1.9438. To convert from kn to m/s, divide by 1.9438. For example, 20 m/s is equal to 38.88 kn, and 15 kn is equal to 7.72 m/s.
- Feet per second (ft/s): To convert from m/s to ft/s, multiply by 3.2808. To convert from ft/s to m/s, divide by 3.2808. For example, 20 m/s is equal to 65.62 ft/s, and 40 ft/s is equal to 12.19 m/s.

## Where meters per second are used

Meters per second are widely used in science and engineering to measure the speed or velocity of various phenomena, such as sound waves, light waves, wind speed, fluid flow, projectile motion, etc.

Meters per second are also used in some countries as the official unit of speed or velocity for road traffic signs and regulations. For example, in Canada, the maximum speed limit on highways is usually 100 km/h, which is equivalent to 27.78 m/s.

Meters per second are also used in sports and athletics to measure the performance of athletes, such as sprinters, swimmers, cyclists, etc.

## Definition of meters per second

According to the SI definition, one meter per second is the speed of a body that covers a distance of one meter in a time of one second.

Mathematically, it can be expressed as:

v = s / t

where v is the speed or velocity in meters per second, s is the distance traveled in meters, and t is the time taken in seconds.

## History of meters per second

The concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc.

The meter was originally defined in 1793 by the French Academy of Sciences as one ten-millionth of the distance from the equator to the North Pole along a meridian through Paris.

The second was originally defined in terms of the Earth’s rotation as one eighty-six thousand four hundredth of a mean solar day.

The combination of these two units resulted in the meter per second as a unit of speed or velocity.

The meter per second was officially adopted as part of the SI system in 1960.

## Example conversions of meters per second to other units

Here are some examples of converting meters per second to other units of speed or velocity:

- 10 m/s = 36 km/h = 22.37 mph = 19.44 kn = 32.81 ft/s
- 5 m/s = 18 km/h = 11.18 mph = 9.72 kn = 16.4 ft/s
- 15 m/s = 54 km/h = 33.55 mph = 29.17 kn = 49.21 ft/s
- 25 m/s = 90 km/h = 55.92 mph = 48.61 kn = 82.02 ft/s
- 50 m/s = 180 km/h = 111.85 mph = 97.22 kn = 164.04 ft/s
- 100 m/s = 360 km/h = 223.69 mph = 194.39 kn = 328.08 ft/s
- 200 m/s = 720 km/h = 447.39 mph = 388.79 kn = 656.17 ft/s
