## 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

## 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.

## History of kilometers 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 kilometer 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.
