Convert Feet Per Second to Kilometers Per Second (fps to km/s) ▶ Conversion Table
How to convert1 kilometer per second (km/s) = 3280.839895 foot per second (fps). Kilometer Per Second (km/s) is a unit of Speed used in Metric system. Foot Per Second (fps) is a unit of Speed used in Standard system. Kilometers per second: A unit of speedKilometers 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 secondKilometers 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:
Where kilometers per second are usedKilometers 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 secondAccording 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 secondThe 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. Example conversions of kilometers per second to other unitsHere are some examples of converting kilometers per second to other units of speed or velocity:
Feet per second: A unit of speedFeet per second (ft/s) is a unit of speed or velocity in the US customary and imperial systems. It measures how fast an object is moving by calculating the distance traveled in feet divided by the time taken in seconds. For example, if a person walks 10 feet in 2 seconds, their speed is 5 ft/s. How to convert feet per secondFeet 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:
Where feet per second are usedFeet per second are mainly used in engineering and aviation to measure the speed or velocity of machines and aircrafts. For example, the speed of sound in air at sea level is about 343 m/s or about 1125 ft/s. The maximum speed of a Boeing 747 jet airliner is about 988 km/h or about 2717 ft/s. The average speed of a bullet fired from a handgun is about 1200 ft/s. Definition of feet per secondAccording to the US customary and imperial systems definition, one foot per second is the speed of a body that covers a distance of one foot in a time of one second. Mathematically, it can be expressed as:
where v is the speed or velocity in feet per second, s is the distance traveled in feet, and t is the time taken in seconds. History of feet per secondThe concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc. The foot was originally derived from the Roman foot which was defined as one third of a yard or about 11.65 inches. 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 foot per second as a unit of speed or velocity. The foot per second was officially adopted as part of the US customary and imperial systems in the late 18th century. Example conversions of feet per second to other unitsHere are some examples of converting feet per second to other units of speed or velocity: 1 ft/s = 0.3048 m/s = 1.09728 km/h = 0.681818 mph = 0.592484 kn = 12 in/s = 0.000189394 mi/s Español Russian Français |
