How to convert1 inch per second (in/s) = 0.09144 kilometer per hour (kph). Inch Per Second (in/s) is a unit of Speed used in Standard system. Kilometer Per Hour (kph) 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 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.
