## 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.

## Definition of Kilometers Per Hour

Kilometers per hour (km/h) is a unit of speed that measures how fast something is moving in terms of kilometers per unit of time. It is commonly used in most countries around the world, except for the United States and some other countries that use the US Standard system of measurement. The speed limit signs on roads and highways are usually expressed in km/h.

One kilometer per hour is equal to 0.27777777777778 meters per second, or 3.6 meters per minute. It can also be converted to other units of speed, such as miles per hour, feet per second, or knots, by using appropriate conversion factors.

## How to Convert Kilometers Per Hour

To convert kilometers per hour to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert kilometers per hour to miles per hour, we need to multiply by 0.6213711922, since there are 0.6213711922 miles in one kilometer. To convert kilometers per hour to meters per second, we need to divide by 3.6, since there are 3.6 seconds in one minute.

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

• To convert 10 km/h to miles per hour (mph), we multiply by 0.6213711922: 10 km/h x 0.6213711922 = 6.213711922 mph
• To convert 20 km/h to feet per second (fps), we multiply by 0.9113444153, since there are 0.9113444153 feet in one meter: 20 km/h x 0.9113444153 = 18.226888306 fps
• To convert 30 km/h to knots (kn), we multiply by 0.5399568035, since there are 0.5399568035 nautical miles in one kilometer: 30 km/h x 0.5399568035 = 16.198704105 kn
• To convert 40 km/h to meters per second (m/s), we divide by 3.6: 40 km/h / 3.6 = 11.111111111 m/s
• To convert 50 km/h to meters per minute (m/min), we multiply by 16.666666667, since there are 16.666666667 minutes in one hour: 50 km/h x 16.666666667 = 833.33333335 m/min
• To convert 60 km/h to centimeters per second (cm/s), we multiply by 1000, since there are 100 centimeters in one meter, and divide by 3.6: 60 km/h x 1000 / 3.6 = 16666.666667 cm/s

## Where Kilometers Per Hour Are Used

Kilometers per hour are mainly used in most countries around the world that use the SI system of measurement or the metric system. 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 100 km/h, which means that it travels a distance of 100 kilometers in one hour. A road sign may indicate a speed limit of 80 km/h, which means that drivers should not exceed this speed on that road section. A train may have a speed of 300 km/h, which means that it covers a distance of 300 kilometers in one hour.

Kilometers 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 kilometers per unit of time.

## History of Kilometers Per Hour

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

The term kilometer first appeared in English in 1810, but it was not until later in the mid-nineteenth century that the use of kilometers per hour became more widespread; before that, other units such as miles per hour or leagues per hour were preferred for expressing speed.

Kilometers per hour have been used ever since as a standard unit of speed for most countries around the world that use the SI system or the metric system. They have also been adopted by some international organizations and conventions, such as the International Civil Aviation Organization and the International System of Units.
