How to convert

1 foot per hour (ft/h) = 3.15657E-06 mile per minute (mi/min). Foot Per Hour (ft/h) is a unit of Speed used in Standard system. Mile Per Minute (mi/min) is a unit of Speed used in Standard system.

Feet Per Hour

Definition of Feet Per Hour

Feet per hour (f/h) is a unit of speed that measures how fast something is moving in terms of feet per unit of time. It is a US Standard unit that is derived from the base unit of length, the foot, and the base unit of time, the hour. It is rarely used however, as the units of feet per second and miles per hour are considered sufficient for most situations.

One foot per hour is equal to 0.000084666666666667 meters per second, or 0.0003048 kilometers per hour. It can also be converted to other units of speed, such as miles per hour, knots, or meters per second, by using appropriate conversion factors.

How to Convert Feet Per Hour

To convert feet per hour to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert feet per hour to miles per hour, we need to multiply by 0.0001893939394, since there are 0.0001893939394 miles in one foot. To convert feet per hour to meters per second, we need to multiply by 0.000084666666666667, since there are 0.000084666666666667 meters in one foot.

Here are some examples of how to convert feet per hour to other units of length in the US Standard system and the SI system:

Where Feet Per Hour Are Used

Feet per hour are mainly used for measuring very slow speeds or velocities of objects or phenomena that move in terms of feet 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 feet per hour, which means that it moves a few feet in one hour. A snail may have a speed of up to 47 feet per hour, which means that it can travel up to 47 feet in one hour.1 A planet may have an orbital velocity of thousands of feet per hour, which means that it covers thousands of feet along its orbit in one hour.

Feet per hour are also used in some other fields where the speed or velocity of an object or phenomenon is measured in terms of feet per unit of time.

History of Feet Per Hour

The origin of feet per hour as a unit of speed can be traced back to the development of the US Standard system and the foot as a unit of length in the late eighteenth century. The foot was defined as one third of a yard based on the English standard foot.

The term foot first appeared in English in the late fourteenth century, but it was not until later in the early nineteenth century that the use of feet per hour became more common; before that, other units such as inches per hour or yards per hour were preferred for expressing speed.

Feet 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 feet 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.

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:

miles per minute = distance in miles / time in minutes

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.
