How to convert

1 mile per minute (mi/min) = 0.0268224 kilometer per second (km/s). Mile Per Minute (mi/min) is a unit of Speed used in Standard system. Kilometer Per Second (km/s) 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:

  • To convert miles per minute to miles per hour, multiply by 60. For example, 3 miles per minute = 3 x 60 = 180 miles per hour.
  • To convert miles per minute to feet per second, multiply by 88. For example, 3 miles per minute = 3 x 88 = 264 feet per second.
  • To convert miles per minute to kilometers per hour, multiply by 96.56. For example, 3 miles per minute = 3 x 96.56 = 289.68 kilometers per hour.
  • To convert miles per minute to meters per second, multiply by 26.8224. For example, 3 miles per minute = 3 x 26.8224 = 80.4672 meters per second.
  • To convert miles per minute to knots, multiply by 51.852. For example, 3 miles per minute = 3 x 51.852 = 155.556 knots.
  • To convert miles per minute to mach, divide by 49.17. For example, 3 miles per minute = 3 / 49.17 = 0.061 mach.

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:

  • In aviation, miles per minute are used to measure the rate of climb or descent of an aircraft. For example, an aircraft that climbs at a rate of 5 miles per minute has a vertical speed of 300 feet per second or 1828 meters per minute.
  • In rail transport, miles per minute are used to measure the speed of trains or locomotives. For example, a train that travels at a speed of 2 miles per minute has a horizontal speed of 120 miles per hour or 193 kilometers per hour.
  • In sports, miles per minute are used to measure the pace or performance of runners or cyclists. For example, a runner who runs a mile in 4 minutes has a pace of 0.25 miles per minute or 15 minutes per mile.
  • In engineering, miles per minute are used to measure the rotational speed of machines or devices. For example, a fan that rotates at a speed of 0.1 miles per minute has an angular speed of 6 degrees per second or 0.105 radians per second.

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:

  • 1 mile per minute = 60 miles per hour
  • 1 mile per minute = 88 feet per second
  • 1 mile per minute = 96.56 kilometers per hour
  • 1 mile per minute = 26.8224 meters per second
  • 1 mile per minute = 51.852 knots
  • 1 mile per minute = 0.0203 mach
  • 1 mile per minute = 0.0000052 light speed
Miles per minute also can be marked as mile/minute.

Kilometers per second: A unit of speed

Kilometers 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 second

Kilometers 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 km/s to m/s, multiply by 1000. To convert from m/s to km/s, divide by 1000. For example, 2 km/s is equal to 2000 m/s, and 500 m/s is equal to 0.5 km/s.
  • Kilometers per hour (km/h): To convert from km/s to km/h, multiply by 3600. To convert from km/h to km/s, divide by 3600. For example, 2 km/s is equal to 7200 km/h, and 100 km/h is equal to 0.028 km/s.
  • Miles per hour (mph): To convert from km/s to mph, multiply by 2236.94. To convert from mph to km/s, divide by 2236.94. For example, 2 km/s is equal to 4473.88 mph, and 60 mph is equal to 0.027 km/s.
  • Knots (kn): To convert from km/s to kn, multiply by 1943.84. To convert from kn to km/s, divide by 1943.84. For example, 2 km/s is equal to 3887.68 kn, and 30 kn is equal to 0.015 km/s.
  • Feet per second (ft/s): To convert from km/s to ft/s, multiply by 3280.84. To convert from ft/s to km/s, divide by 3280.84. For example, 2 km/s is equal to 6561.68 ft/s, and 100 ft/s is equal to 0.03 km/s.
  • Miles per second (mi/s): To convert from km/s to mi/s, multiply by 0.621371. To convert from mi/s to km/s, divide by 0.621371. For example, 2 km/s is equal to 1.24 mi/s, and 1 mi/s is equal to 1.61 km/s.

Where kilometers per second are used

Kilometers 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 human-made 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 second

According 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 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.

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 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.
