How to convert

1 foot per hour (ft/h) = 0.084666667 millimeter per second (mm/s). Foot Per Hour (ft/h) is a unit of Speed used in Standard system. Millimeter Per Second (mm/s) is a unit of Speed used in Metric 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:

  • To convert 10 f/h to miles per hour (mph), we multiply by 0.0001893939394: 10 f/h x 0.0001893939394 = 0.001893939394 mph
  • To convert 20 f/h to feet per second (fps), we divide by 3600, since there are 3600 seconds in one hour: 20 f/h / 3600 = 0.005555555556 fps
  • To convert 30 f/h to knots (kn), we multiply by 0.0001645788337, since there are 0.0001645788337 nautical miles in one foot: 30 f/h x 0.0001645788337 = 0.004937365011 kn
  • To convert 40 f/h to meters per second (m/s), we multiply by 0.000084666666666667: 40 f/h x 0.000084666666666667 = 0.003386666667 m/s
  • To convert 50 f/h to meters per minute (m/min), we multiply by 0.00508, since there are 0.00508 meters in one foot: 50 f/h x 0.00508 = 0.254 m/min
  • To convert 60 f/h to centimeters per second (cm/s), we multiply by 100, since there are 100 centimeters in one meter, and multiply by 0.000084666666666667: 60 f/h x 100 x 0.000084666666666667 = 0.508 cm/s

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.

Example Conversions of Feet Per Hour to Other Units

Here are some examples of how to convert feet per hour to other units of speed, using the conversion factors given above:

  • To convert 100 f/h to miles per hour, we multiply by 0.0001893939394: 100 f/h x 0.0001893939394 = 0.01893939394 mph
  • To convert 200 f/h to feet per second, we divide by 3600: 200 f/h / 3600 = 0.05555555556 fps
  • To convert 300 f/h to knots, we multiply by 0.0001645788337: 300 f/h x 0.0001645788337 = 0.04937365011 kn
  • To convert 400 f/h to meters per second, we multiply by 0.000084666666666667: 400 f/h x 0.000084666666666667 = 0.03386666667 m/s
  • To convert 500 f/h to meters per minute, we multiply by 0.00508: 500 f/h x 0.00508 = 2.54 m/min
  • To convert 600 f/h to centimeters per second, we multiply by 100 and multiply by 0.000084666666666667: 600 f/h x 100 x 0.000084666666666667 = 5.08 cm/s
  • To convert 700 f/h to millimeters per minute, we multiply by 1000, since there are 1000 millimeters in one meter, and multiply by 0.00508: 700 f/h x 1000 x 0.00508 = 3556 mm/min
Foot per hour also can be marked as foot/hour.

How to convert millimeters per second

Where millimeters per second are used

Millimeters per second are mainly used in microbiology and nanotechnology to measure the speed or velocity of microscopic organisms and processes.

For example, the average speed of a bacterium such as Escherichia coli is about 10-20 micrometers per second, which is equivalent to 0.01-0.02 mm/s.

The average speed of a virus such as influenza A virus is about 1 micrometer per second, which is equivalent to 0.001 mm/s.

The average speed of a nanorobot such as a DNA origami walker is about 4 nanometers per second, which is equivalent to 0.000004 mm/s.

Definition of millimeters per second

According to the SI definition, one millimeter per second is the speed of a body that covers a distance of one millimeter in a time of one second.

Mathematically, it can be expressed as:

where v is the speed or velocity in millimeters per second, s is the distance traveled in millimeters, and t is the time taken in seconds.

History of millimeters 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 millimeter was originally derived from the meter in the late 18th century as one thousandth of a meter.

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 millimeter per second as a unit of speed or velocity.

The millimeter per second was officially adopted as part of the SI system in 1960.
