How to convert1 knot (kt) = 44.448 kilometer per day (km/day). Knot (kt) is a unit of Speed used in Standard system. Kilometer Per Day (km/day) is a unit of Speed used in Metric system. 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.

Kilometers Per DayDefinition of Kilometers Per DayKilometers per day (km/d) is a unit of speed that measures how fast something is moving in terms of kilometers per unit of time. It is a metric unit that is derived from the base unit of length, the kilometer, and the base unit of time, the day. It is rarely used however, as the units of kilometers per hour and meters per second are considered sufficient for most situations. One kilometer per day is equal to 0.011574074074074 meters per second, or 0.041666666666667 kilometers per hour. 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 DayTo convert kilometers per day to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert kilometers per day to miles per hour, we need to multiply by 0.0254, since there are 0.0254 miles in one kilometer. To convert kilometers per day to meters per second, we need to multiply by 0.011574074074074, since there are 0.011574074074074 meters in one kilometer. Here are some examples of how to convert kilometers per day to other units of length in the US Standard system and the SI system:
Where Kilometers Per Day Are UsedKilometers per day are mainly used for measuring the average speed or distance traveled by an object or phenomenon over a period of time that is measured in days or longer. They are often used in fields such as travel, fitness, sports, and geography, where the speed or distance traveled by an object or phenomenon is measured in terms of kilometers per unit of time. For example, a person may travel an average of 100 km/d on a road trip across a country, which means that they cover an average distance of 100 kilometers in one day. A runner may run an average of 5 km/d as part of their training routine, which means that they run a distance of 5 kilometers in one day. A planet may have an orbital velocity of thousands of kilometers per day, which means that it covers thousands of kilometers along its orbit in one day. Kilometers per day are also used in some other fields where the speed or distance traveled by an object or phenomenon is measured in terms of kilometers per unit of time. History of Kilometers Per DayThe origin of kilometers per day 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 thousand meters based on the French standard meter. The term kilometer first appeared in English in 1810, but it was not until later in the midlate 19 th century that the use of kilometers per day became more common; before that, other units such as miles per day or leagues per day were preferred for expressing speed. Kilometers per day have been used ever since as a standard unit of speed for measuring the average speed or distance traveled by an object or phenomenon over a period of time that is measured in days or longer. They have also been adopted by some international organizations and conventions, such as the International System of Units and the International Astronomical Union.
