How to convert1 foot per hour (ft/h) = 0.000164579 knot (kt). Foot Per Hour (ft/h) is a unit of Speed used in Standard system. Knot (kt) is a unit of Speed used in Standard system. 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.

KnotsDefinition of KnotsKnots, commonly denoted kn, is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h (approximately 1.151 mph or 0.514 m/s). It is the standard unit of speed used in meteorology, and in maritime and air navigation. A vessel travelling at 1 kn along a meridian travels approximately one minute of geographic latitude in one hour. How to Convert KnotsTo convert knots to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert knots to kilometers per hour, we need to multiply by 1.852, since there are 1.852 kilometers in one nautical mile. To convert knots to meters per second, we need to divide by 3.6, since there are 3.6 seconds in one hour. Here are some examples of how to convert knots to other units of length in the US Standard system and the SI system:
Where Knots Are UsedKnots are used in various fields of science and technology where the speed and direction of movement of objects or phenomena are measured or applied in relation to water or air currents. For example:
History of KnotsThe origin of knots as a unit of speed can be traced back to the ancient practice of measuring the speed of ships by using a device called a chip log or logline. This device consisted of a wooden board attached to a rope with knots tied at regular intervals along its length. The board was thrown overboard from the stern of the ship and allowed to drag behind it while the rope was let out for a fixed amount of time (usually measured by a sandglass). The number of knots that passed over the rail of the ship during that time indicated the speed of the ship in nautical miles per hour. The first recorded use of this method was by the Phoenicians around the second millennium BCE. The device was later improved and standardized by various civilizations such as the Greeks, Romans, Arabs, Vikings, Chinese, and Europeans. The length of the nautical mile and the spacing of the knots varied from place to place and from time to time until they were fixed by international agreement in the late nineteenth century. The term knot was derived from the Old English word cnotta meaning “a knot”. It was first used as a unit of speed by English sailors in the early seventeenth century.
