How to convert1 inch per second (in/s) = 2.54E05 kilometer per second (km/s). Inch Per Second (in/s) is a unit of Speed used in Standard system. Kilometer Per Second (km/s) is a unit of Speed used in Metric system. Inches per second: A unit of speedInches per second ( in/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 inches divided by the time taken in seconds. For example, if a worm travels 2 inches in 1 second, its speed is 2 in/s. How to convert inches per secondInches 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 inches per second are usedInches per second are mainly used in engineering and manufacturing to measure the speed or velocity of machines and processes. For example, the cutting speed of a lathe or a milling machine is often given in inches per minute, which is equivalent to inches per second divided by 60. The rotational speed of a hard disk drive is often given in revolutions per minute, which can be converted to inches per second by multiplying by the circumference of the disk. The flow rate of a fluid through a pipe or a nozzle is often given in gallons per minute, which can be converted to inches per second by multiplying by the crosssectional area of the pipe or the nozzle. Definition of inches per secondAccording to the US customary and imperial systems definition, one inch per second is the speed of a body that covers a distance of one inch in a time of one second. Mathematically, it can be expressed as:
where v is the speed or velocity in inches per second, s is the distance traveled in inches, and t is the time taken in seconds. History of inches per secondThe concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc. The inch was originally derived from the Roman uncia which was one twelfth of a Roman foot or about 0.97 inches . The second was originally defined in terms of the Earth’s rotation as one eightysix thousand four hundredth of a mean solar day. The combination of these two units resulted in the inch per second as a unit of speed or velocity. The inch per second was officially adopted as part of the US customary and imperial systems in the late 18th century. Example conversions of inches per second to other unitsHere are some examples of converting inches per second to other units of speed or velocity: 1 in/s = 0.0254 m/s = 0.09144 km/h = 0.0568182 mph = 0.0493737 kn = 0.0833333 ft/s = 1.5783x10 5 mi/s 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 humanmade 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 tenmillionth 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 eightysix 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.
