How to convert

1 centimeter per second (cm/s) = 0.022369363 mile per hour (mph). Centimeter Per Second (cm/s) is a unit of Speed used in Metric system. Mile Per Hour (mph) is a unit of Speed used in Standard system.

Centimeters per second: A unit of speed

Centimeters per second (cm/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 centimeters divided by the time taken in seconds. For example, if a snail travels 10 centimeters in 10 seconds, its speed is 1 cm/s.

How to convert centimeters per second

Centimeters 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:

  • Meters per second (m/s): To convert from cm/s to m/s, divide by 100. To convert from m/s to cm/s, multiply by 100. For example, 1 cm/s is equal to 0.01 m/s, and 10 m/s is equal to 1000 cm/s.
  • Kilometers per hour (km/h): To convert from cm/s to km/h, multiply by 0.036. To convert from km/h to cm/s, divide by 0.036. For example, 1 cm/s is equal to 0.036 km/h, and 50 km/h is equal to 1388.89 cm/s.
  • Miles per hour (mph): To convert from cm/s to mph, multiply by 0.0223694. To convert from mph to cm/s, divide by 0.0223694. For example, 1 cm/s is equal to 0.0223694 mph, and 30 mph is equal to 1341.12 cm/s.
  • Knots (kn): To convert from cm/s to kn, multiply by 0.0194384. To convert from kn to cm/s, divide by 0.0194384. For example, 1 cm/s is equal to 0.0194384 kn, and 15 kn is equal to 771.61 cm/s.
  • Feet per second (ft/s): To convert from cm/s to ft/s, multiply by 0.0328084. To convert from ft/s to cm/s, divide by 0.0328084. For example, 1 cm/s is equal to 0.0328084 ft/s, and 40 ft/s is equal to 1219.2 cm/s.
  • Miles per second (mi/s): To convert from cm/s to mi/s, multiply by 0.00000621371. To convert from mi/s to cm/s, divide by 0.00000621371. For example, 1 cm/s is equal to 0.00000621371 mi/s, and 1 mi/s is equal to 160934 cm/s.

Where centimeters per second are used

Centimeters per second are mainly used in biology and medicine to measure the speed or velocity of small organisms and processes.

For example, the average speed of a common snail is about 1 cm/s.

The average speed of blood flow in capillaries is about 0.5 cm/s.

The average speed of nerve impulses in the human body is about 100 cm/s.

Definition of centimeters per second

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

Mathematically, it can be expressed as:

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

History of centimeters 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 centimeter was originally derived from the meter in the late 18th century as one hundredth of a meter.

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 centimeter per second as a unit of speed or velocity.

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

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 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
Miles per hour also can be marked as mile/hour and mi/h.
