Convert Kilometers Per Hour to Light Speed (kph to ls) ▶ Conversion Table
How to convert1 light speed (ls) = 1079252849 kilometer per hour (kph). Light Speed (ls) is a unit of Speed used in Metric system. Kilometer Per Hour (kph) is a unit of Speed used in Metric system. Light SpeedDefinition of Light SpeedLight speed, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour). It is the speed at which light waves propagate through vacuum, and also the upper limit for the speed at which any form of matter or energy can travel through space. Light speed is an essential parameter in the theories of relativity and electromagnetism, and has relevance beyond the context of light and electromagnetic waves. How to Convert Light SpeedTo convert light speed to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert light speed to kilometers per hour, we need to multiply by 3,600, since there are 3,600 seconds in one hour. To convert light speed to miles per hour, we need to multiply by 2.2369362920544, since there are 2.2369362920544 miles in one kilometer. Here are some examples of how to convert light speed to other units of length in the US Standard system and the SI system:
Where Light Speed Is UsedLight speed is used in various fields of science and technology where the properties and behavior of light and electromagnetic waves are studied or applied. For example:
History of Light SpeedThe concept of light speed has a long history that spans across different cultures and disciplines. Some of the milestones in its development are:

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 tenthousandth 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 midnineteenth 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.
