Convert Kilometers Per Minute to Miles Per Minute (km/min to mi/min) ▶
How to convert
1 mile per minute (mi/min) = 1.609344001 kilometer per minute (km/min). Mile Per Minute (mi/min) is a unit of Speed used in Standard system. Kilometer Per Minute (km/min) is a unit of Speed used in Metric system.
Miles per minute: a unit of speed
Miles per minute is a unit of speed that measures how many miles an object travels in one minute. It is commonly used in the United States and some other countries that use the imperial or US customary system of measurement. One mile per minute is equal to 60 miles per hour or 96.56 kilometers per hour.
How to convert miles per minute
To convert miles per minute to other units of speed, we can use the following formulas:
Where miles per minute are used
Miles per minute are used in various contexts and applications that involve speed or distance measurement. Some examples are:
Definition of the miles per minute
Miles per minute is defined as the ratio of the distance traveled in miles to the time elapsed in minutes. Mathematically, it can be expressed as:
Alternatively, it can be derived from the definition of the mile and the definition of the minute. A mile is defined as the length of one arc-minute along the equator of the Earth, which is approximately equal to 1609 meters. A minute is defined as one sixtieth of an hour, which is equal to 60 seconds.
History of miles per minute
The origin of the mile as a unit of length can be traced back to ancient Rome, where it was defined as one thousand paces or steps (mille passus in Latin). The Roman mile was about 1480 meters long and was divided into eight stadia or furlongs, each consisting of 125 paces.
The origin of the minute as a unit of time can be traced back to ancient Babylon, where it was defined as one sixtieth of an hour (mina in Babylonian). The Babylonian hour was based on the sexagesimal system of counting, which used base 60 instead of base 10. The Babylonian minute was about 4 seconds long and was divided into 60 seconds.
The combination of the mile and the minute as a unit of speed was first used in the 17th century by astronomers and navigators, who needed to measure the angular speed of celestial objects or the linear speed of ships. For example, in 1676, the Danish astronomer Ole Romer used miles per minute to estimate the speed of light by observing the eclipses of Jupiter’s moons.
The use of miles per minute as a unit of speed became more widespread in the 18th and 19th centuries, especially in the fields of transportation and engineering. For example, in 1804, the British engineer Richard Trevithick built the first steam locomotive that could reach a speed of one mile per minute. In 1903, the American brothers Orville and Wilbur Wright made the first powered flight that could achieve a speed of two miles per minute.
The use of miles per minute as a unit of speed declined in the 20th and 21st centuries, as more countries adopted the metric system and its units of speed, such as kilometers per hour or meters per second. However, miles per minute are still used in some contexts and applications, especially in the United States and some other countries that use the imperial or US customary system of measurement.
Example conversions of miles per minute to other units
Here are some examples of converting miles per minute to other units of speed:
Kilometers per minute: A unit of speed
Kilometers per minute (km/min) 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 minutes. For example, if a train travels 3 kilometers in 2 minutes, its speed is 1.5 km/min.
How to convert kilometers per minute
Kilometers per minute 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 minute are used
Kilometers per minute are mainly used in transportation and sports to measure the speed or velocity of vehicles and athletes.
For example, the maximum speed of a Formula One car is about 5 km/min or about 300 km/h.
The average speed of a marathon runner is about 0.35 km/min or about 21 km/h.
The cruising speed of a commercial jet airliner is about 16.67 km/min or about 1000 km/h.
Definition of kilometers per minute
According to the SI definition, one kilometer per minute is the speed of a body that covers a distance of one kilometer in a time of one minute.
Mathematically, it can be expressed as:
where v is the speed or velocity in kilometers per minute, s is the distance traveled in kilometers, and t is the time taken in minutes.
History of kilometers per minute
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 derived from the French kilometer which was defined as one thousand meters.
The minute was originally derived from the Babylonian sexagesimal system which divided an hour into sixty minutes.
The combination of these two units resulted in the kilometer per minute as a unit of speed or velocity.
The kilometer per minute was officially adopted as part of the SI system in 1960.
Example conversions of kilometers per minute to other units
Here are some examples of converting kilometers per minute to other units of speed or velocity:
1 km/min = 16.6667 m/s = 60 km/h = 37.2823mph = 32.3974kn = 3280.8399 ft/min = 39370.0787 in/min
