How to convert

1 kilometer per second (km/s) = 53686.47101 mile per day (mi/day). Kilometer Per Second (km/s) is a unit of Speed used in Metric system. Mile Per Day (mi/day) is a unit of Speed used in Standard system.

Kilometers per second: A unit of speed

Kilometers per second (km/s) is a unit of speed or velocity in the International System of Units (SI). It measures how fast an object is moving by calculating the distance traveled in kilometers divided by the time taken in seconds. For example, if a rocket travels 10 kilometers in 5 seconds, its speed is 2 km/s.

How to convert kilometers per second

Kilometers per second can be converted to other units of speed or velocity by using simple conversion factors. Here are some common units and their conversion factors:

  • Meters per second (m/s): To convert from km/s to m/s, multiply by 1000. To convert from m/s to km/s, divide by 1000. For example, 2 km/s is equal to 2000 m/s, and 500 m/s is equal to 0.5 km/s.
  • Kilometers per hour (km/h): To convert from km/s to km/h, multiply by 3600. To convert from km/h to km/s, divide by 3600. For example, 2 km/s is equal to 7200 km/h, and 100 km/h is equal to 0.028 km/s.
  • Miles per hour (mph): To convert from km/s to mph, multiply by 2236.94. To convert from mph to km/s, divide by 2236.94. For example, 2 km/s is equal to 4473.88 mph, and 60 mph is equal to 0.027 km/s.
  • Knots (kn): To convert from km/s to kn, multiply by 1943.84. To convert from kn to km/s, divide by 1943.84. For example, 2 km/s is equal to 3887.68 kn, and 30 kn is equal to 0.015 km/s.
  • Feet per second (ft/s): To convert from km/s to ft/s, multiply by 3280.84. To convert from ft/s to km/s, divide by 3280.84. For example, 2 km/s is equal to 6561.68 ft/s, and 100 ft/s is equal to 0.03 km/s.
  • Miles per second (mi/s): To convert from km/s to mi/s, multiply by 0.621371. To convert from mi/s to km/s, divide by 0.621371. For example, 2 km/s is equal to 1.24 mi/s, and 1 mi/s is equal to 1.61 km/s.

Where kilometers per second are used

Kilometers per second are mainly used in astronomy and space science to measure the speed or velocity of celestial bodies and spacecrafts.

For example, the Earth orbits the Sun at an average speed of about 30 km/s.

The Moon orbits the Earth at an average speed of about 1 km/s.

The International Space Station orbits the Earth at an average speed of about 7.66 km/s.

The Voyager 1 spacecraft, which is the farthest human-made object from Earth, travels at a speed of about 17 km/s.

The speed of light in a vacuum is about 300000 km/s.

Definition of kilometers per second

According to the SI definition, one kilometer per second is the speed of a body that covers a distance of one kilometer in a time of one second.

Mathematically, it can be expressed as:

where v is the speed or velocity in kilometers per second, s is the distance traveled in kilometers, and t is the time taken in seconds.

History of kilometers per second

The concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc.

The kilometer was originally defined in 1793 by the French Academy of Sciences as one ten-millionth of the distance from the equator to the North Pole along a meridian through Paris.

The second was originally defined in terms of the Earth’s rotation as one eighty-six thousand four hundredth of a mean solar day.

The combination of these two units resulted in the kilometer per second as a unit of speed or velocity.

The kilometer per second was officially adopted as part of the SI system in 1960.

Kilometers per second also can be marked as km/s and kilometres per second(alternative British English spelling in UK).

Miles Per Day

Definition of Miles Per Day

Miles per day (mi/d) is a unit of speed that measures how fast something is moving in terms of miles per unit of time. It is commonly used in the United States, the United Kingdom, and some other countries that use the US Standard system of measurement or have close historical ties with them. It is often 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.

One mile per day is equal to 0.0416666667 miles per hour, or 0.0185185185 meters per second. It can also be converted to other units of speed, such as kilometers per hour, feet per second, or knots, by using appropriate conversion factors.

How to Convert Miles Per Day

To convert miles per day to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert miles per day to kilometers per hour, we need to multiply by 1.609344, since there are 1.609344 kilometers in one mile. To convert miles per day to meters per second, we need to multiply by 0.018518518518519, since there are 0.018518518518519 meters in one mile.

Here are some examples of how to convert miles per day to other units of length in the US Standard system and the SI system:

  • To convert 10 mi/d to kilometers per hour (km/h), we multiply by 1.609344: 10 mi/d x 1.609344 = 16.09344 km/h
  • To convert 20 mi/d to feet per second (fps), we multiply by 0.05787037037037, since there are 0.05787037037037 feet in one meter: 20 mi/d x 0.05787037037037 = 1.157407407407 fps
  • To convert 30 mi/d to knots (kn), we multiply by 0.03626111111, since there are 0.0362611111 nautical miles in one mile: 30 mi/d x 0.0362611111 = 1.08783333 kn
  • To convert 40 mi/d to meters per second (m/s), we multiply by 0.018518518518519: 40 mi/d x 0.018518518518519 = 0.740740740741 m/s
  • To convert 50 mi/d to meters per minute (m/min), we multiply by 1.11111, since there are 1.11111 minutes in one hour: 50 mi/d x 1.11111 = 55.555555556 m/min
  • To convert 60 mi/d to centimeters per second (cm/s), we multiply by 100, since there are 100 centimeters in one meter, and multiply by 0.018518518518519: 60 mi/d x 100 x 0.018518518518519 = 111.11111 cm/s

Where Miles Per Day Are Used

Miles 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 miles per unit of time.

For example, a person may travel an average of 100 mi/d on a road trip across a country, which means that they cover an average distance of 100 miles in one day. A runner may run an average of 5 mi/d as part of their training routine, which means that they run a distance of 5 miles in one day. A planet may have an orbital velocity of thousands of miles per day, which means that it covers thousands of miles along its orbit in one day.

Miles 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 miles per unit of time.

History of Miles Per Day

The origin of miles per day as a unit of speed can be traced back to the development of the US Standard system and the mile as a unit of length in the late eighteenth century. The mile was defined as one thousand six hundred and nine meters (or eight furlongs) based on the English statute mile.

The term mile first appeared in English in the late fourteenth century, but it was not until later in the early nineteenth century that the use of miles per day became more common; before that, other units such as miles per hour or leagues per day were preferred for expressing speed.

Miles 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.
