Convert Feet Per Second to Feet Per Hour (fps to ft/h) ▶
How to convert
1 foot per hour (ft/h) = 0.016666667 foot per second (fps). Foot Per Hour (ft/h) is a unit of Speed used in Standard system. Foot Per Second (fps) 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.

Here are some examples of how to convert feet per hour to other units of speed, using the conversion factors given above:
Feet per second: A unit of speed
Feet per second (ft/s) is a unit of speed or velocity in the US customary and imperial systems. It measures how fast an object is moving by calculating the distance traveled in feet divided by the time taken in seconds. For example, if a person walks 10 feet in 2 seconds, their speed is 5 ft/s.
How to convert feet per second
Feet 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 feet per second are used
Feet per second are mainly used in engineering and aviation to measure the speed or velocity of machines and aircrafts.
For example, the speed of sound in air at sea level is about 343 m/s or about 1125 ft/s.
The maximum speed of a Boeing 747 jet airliner is about 988 km/h or about 2717 ft/s.
The average speed of a bullet fired from a handgun is about 1200 ft/s.
Definition of feet per second
According to the US customary and imperial systems definition, one foot per second is the speed of a body that covers a distance of one foot in a time of one second.
Mathematically, it can be expressed as:
where v is the speed or velocity in feet per second, s is the distance traveled in feet, and t is the time taken in seconds.
History of feet 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 foot was originally derived from the Roman foot which was defined as one third of a yard or about 11.65 inches.
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 foot per second as a unit of speed or velocity.
The foot per second was officially adopted as part of the US customary and imperial systems in the late 18th century.
Example conversions of feet per second to other units
Here are some examples of converting feet per second to other units of speed or velocity:
1 ft/s = 0.3048 m/s = 1.09728 km/h = 0.681818 mph = 0.592484 kn = 12 in/s = 0.000189394 mi/s
