## How to convert

1 meter per second (m/s) = 1000 millimeter per second (mm/s). Meter Per Second (m/s) is a unit of Speed used in Metric system. Millimeter Per Second (mm/s) is a unit of Speed used in Metric system.

## 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:

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

Meters per second also can be marked as m/s and metres per second(alternative British English spelling in UK).
