Kilometers Per Day

Definition of Kilometers Per Day

Kilometers 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 Day

To 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:

  • To convert 10 km/d to miles per hour (mph), we multiply by 0.0254: 10 km/d x 0.0254 = 0.254 mph
  • To convert 20 km/d to feet per second (fps), we multiply by 0.0378788, since there are 0.037878788 feet in one meter: 20 km/d x 0.037878788 = 0.75757576 fps
  • To convert 30 km/d to knots (kn), we multiply by 0.0218645833, since there are 0.021864583 nautical miles in one kilometer: 30 km/d x 0.0218645833 = 0.6559375 kn
  • To convert 40 km/d to meters per second (m/s), we multiply by 0.011574074074074: 40 km/d x 0.011574074074074 = 0.462962962963 m/s
  • To convert 50 km/d to meters per minute (m/min), we multiply by 0.6944444, since there are 0.6944444 minutes in one hour: 50 km/d x 0.6944444 = 34.722222 m/min
  • To convert 60 km/d to centimeters per second (cm/s), we multiply by 100, since there are 100 centimeters in one meter, and multiply by 0.011574074074074: 60 km/d x 100 x 0.011574074074074 = 69.444444 cm/s

Where Kilometers Per Day Are Used

Kilometers 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 Day

The 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 mid-late 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.

Where Kilometers Per Hour Are Used

Kilometers 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 Hour

The 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.
