How to convert1 mile per second (mi/s) = 19008000 foot per hour (ft/h). Mile Per Second (mi/s) is a unit of Speed used in Standard system. Foot Per Hour (ft/h) is a unit of Speed used in Standard system. Miles per second: A unit of speedMiles per second (mi/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 miles divided by the time taken in seconds. For example, if a bullet travels 1 mile in 0.5 seconds, its speed is 2 mi/s. How to convert miles per secondMiles 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 miles per second are usedMiles per second are mainly used in physics and astronomy to measure the speed or velocity of very fast objects and phenomena. For example, the escape velocity of the Earth is about 11 km/s or about 6.84 mi/s. The orbital velocity of the Earth around the Sun is about 30 km/s or about 18.64 mi/s. The speed of light in a vacuum is about 300000 km/s or about 186282 mi/s. The speed of sound in air at sea level is about 343 m/s or about 0.213139 mi/s. Definition of miles per secondAccording to the US customary and imperial systems definition, one mile per second is the speed of a body that covers a distance of one mile in a time of one second. Mathematically, it can be expressed as:
where v is the speed or velocity in miles per second, s is the distance traveled in miles, and t is the time taken in seconds. History of miles per secondThe concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc. The mile was originally derived from the Roman mile which was defined as one thousand paces or about 5000 Roman feet. The second was originally defined in terms of the Earth’s rotation as one eightysix thousand four hundredth of a mean solar day. The combination of these two units resulted in the mile per second as a unit of speed or velocity. The mile per second was officially adopted as part of the US customary and imperial systems in the late 18th century.

Feet Per HourDefinition of Feet Per HourFeet 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 HourTo 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 UsedFeet 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 HourThe 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.
