Convert Meters Per Hour to Kilometers Per Second (m/h to km/s) ▶ Conversion Table
How to convert1 kilometer per second (km/s) = 3600000 meter per hour (m/h). Kilometer Per Second (km/s) is a unit of Speed used in Metric system. Meter Per Hour (m/h) is a unit of Speed used in Metric system. Kilometers per second: A unit of speedKilometers per second (km/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 kilometers divided by the time taken in seconds. For example, if a rocket travels 10 kilometers in 5 seconds, its speed is 2 km/s. How to convert kilometers per secondKilometers 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:
Where kilometers per second are usedKilometers per second are mainly used in astronomy and space science to measure the speed or velocity of celestial bodies and spacecrafts. For example, the Earth orbits the Sun at an average speed of about 30 km/s. The Moon orbits the Earth at an average speed of about 1 km/s. The International Space Station orbits the Earth at an average speed of about 7.66 km/s. The Voyager 1 spacecraft, which is the farthest humanmade object from Earth, travels at a speed of about 17 km/s. The speed of light in a vacuum is about 300000 km/s. Definition of kilometers per secondAccording to the SI definition, one kilometer per second is the speed of a body that covers a distance of one kilometer in a time of one second. Mathematically, it can be expressed as:
where v is the speed or velocity in kilometers per second, s is the distance traveled in kilometers, and t is the time taken in seconds. History of kilometers per secondThe 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 tenmillionth 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 eightysix thousand four hundredth of a mean solar day. The combination of these two units resulted in the kilometer per second as a unit of speed or velocity. The kilometer per second was officially adopted as part of the SI system in 1960.

Meters Per HourDefinition of Meters Per HourMeters per hour (m/h) is a unit of speed that measures how fast something is moving in terms of meters per unit of time. It is a metric unit that is derived from the base unit of length, the meter, and the base unit of time, the hour. It is rarely used however, as the units of meters per second and kilometers per hour are considered sufficient for most situations. One meter per hour is equal to 0.00027777777777778 meters per second, or 0.001 kilometers per hour. It can also be converted to other units of speed, such as feet per second, miles per hour, or knots, by using appropriate conversion factors. How to Convert Meters Per HourTo convert meters per hour to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert meters per hour to feet per second, we need to multiply by 0.0009113444153, since there are 0.0009113444153 feet in one meter. To convert meters per hour to kilometers per hour, we need to multiply by 0.001, since there are 0.001 kilometers in one meter. Here are some examples of how to convert meters per hour to other units of length in the US Standard system and the SI system:
Where Meters Per Hour Are UsedMeters per hour are mainly used for measuring very slow speeds or velocities of objects or phenomena that move in terms of meters per unit of time. They are often used in scientific fields such as geology, biology, astronomy, and physics, where the speed or velocity of an object or phenomenon is very small compared to the usual units of speed. For example, a glacier may have a speed of a few meters per hour, which means that it moves a few meters in one hour. A snail may have a speed of up to 47 meters per hour, which means that it can travel up to 47 meters in one hour. A planet may have an orbital velocity of thousands of meters per hour, which means that it covers thousands of meters along its orbit in one hour. Meters per hour are also used in some other fields where the speed or velocity of an object or phenomenon is measured in terms of meters per unit of time. History of Meters Per HourThe origin of meters per hour as a unit of speed can be traced back to the development of the metric system and the meter as a unit of length in the late eighteenth century. The meter was defined as one tenmillionth of the distance from the equator to the North Pole along a meridian through Paris. The term meter first appeared in English in 1797, but it was not until later in the early nineteenth century that the use of meters per hour became more common; before that, other units such as feet per hour or leagues per hour were preferred for expressing speed. Meters per hour have been used ever since as a standard unit of speed for measuring very slow speeds or velocities of objects or phenomena that move in terms of meters per unit of time. They have also been adopted by some international organizations and conventions, such as the International System of Units and the International Astronomical Union.
