Convert Feet Per Hour to Kilometers Per Hour (ft/h to kph) ▶ Conversion Table
How to convert1 kilometer per hour (kph) = 3280.8399 foot per hour (ft/h). Kilometer Per Hour (kph) is a unit of Speed used in Metric system. Foot Per Hour (ft/h) is a unit of Speed used in Standard system. Kilometers Per HourDefinition of Kilometers Per HourKilometers per hour (km/h) is a unit of speed that measures how fast something is moving in terms of kilometers per unit of time. It is commonly used in most countries around the world, except for the United States and some other countries that use the US Standard system of measurement. The speed limit signs on roads and highways are usually expressed in km/h. One kilometer per hour is equal to 0.27777777777778 meters per second, or 3.6 meters per minute. It can also be converted to other units of speed, such as miles per hour, feet per second, or knots, by using appropriate conversion factors. How to Convert Kilometers Per HourTo convert kilometers per hour to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert kilometers per hour to miles per hour, we need to multiply by 0.6213711922, since there are 0.6213711922 miles in one kilometer. To convert kilometers per hour to meters per second, we need to divide by 3.6, since there are 3.6 seconds in one minute. Here are some examples of how to convert kilometers per hour to other units of length in the US Standard system and the SI system:
Where Kilometers Per Hour Are UsedKilometers per hour are mainly used in most countries around the world that use the SI system of measurement or the metric system. They are often used for car speeds and road signs, as well as for trains, planes, boats, and bicycles. For example, a car may have a speed of 100 km/h, which means that it travels a distance of 100 kilometers in one hour. A road sign may indicate a speed limit of 80 km/h, which means that drivers should not exceed this speed on that road section. A train may have a speed of 300 km/h, which means that it covers a distance of 300 kilometers in one hour. Kilometers per hour are also used in some other fields, such as sports, weather, and astronomy, where the speed or velocity of an object or phenomenon is measured in kilometers per unit of time. History of Kilometers Per HourThe origin of kilometers per hour as a unit of speed can be traced back to the development of the metric system and the kilometer as a unit of length in the late eighteenth century. The kilometer was defined as one ten-thousandth of the distance from the equator to the North Pole along a meridian through Paris. The term kilometer first appeared in English in 1810, but it was not until later in the mid-nineteenth century that the use of kilometers per hour became more widespread; before that, other units such as miles per hour or leagues per hour were preferred for expressing speed. Kilometers per hour have been used ever since as a standard unit of speed for most countries around the world that use the SI system or the metric system. They have also been adopted by some international organizations and conventions, such as the International Civil Aviation Organization and the International System of Units. Example Conversions of Kilometers Per Hour to Other UnitsHere are some examples of how to convert kilometers per hour to other units of speed, using the conversion factors given above:
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.
