Convert Inches Per Minute to Kilometers Per Minute (in/min to km/min) ▶
How to convert
1 kilometer per minute (km/min) = 39370.0787 inch per minute (in/min). Kilometer Per Minute (km/min) is a unit of Speed used in Metric system. Inch Per Minute (in/min) is a unit of Speed used in Standard system.
Kilometers per minute: A unit of speed
Kilometers per minute (km/min) 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 minutes. For example, if a train travels 3 kilometers in 2 minutes, its speed is 1.5 km/min.
How to convert kilometers per minute
Kilometers per minute 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 minute are used
Kilometers per minute are mainly used in transportation and sports to measure the speed or velocity of vehicles and athletes.
For example, the maximum speed of a Formula One car is about 5 km/min or about 300 km/h.
The average speed of a marathon runner is about 0.35 km/min or about 21 km/h.
The cruising speed of a commercial jet airliner is about 16.67 km/min or about 1000 km/h.
Definition of kilometers per minute
According to the SI definition, one kilometer per minute is the speed of a body that covers a distance of one kilometer in a time of one minute.
Mathematically, it can be expressed as:
where v is the speed or velocity in kilometers per minute, s is the distance traveled in kilometers, and t is the time taken in minutes.
History of kilometers per minute
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 derived from the French kilometer which was defined as one thousand meters.
The minute was originally derived from the Babylonian sexagesimal system which divided an hour into sixty minutes.
The combination of these two units resulted in the kilometer per minute as a unit of speed or velocity.
The kilometer per minute was officially adopted as part of the SI system in 1960.
Example conversions of kilometers per minute to other units
Here are some examples of converting kilometers per minute to other units of speed or velocity:
1 km/min = 16.6667 m/s = 60 km/h = 37.2823mph = 32.3974kn = 3280.8399 ft/min = 39370.0787 in/min
Inches Per Minute
Definition of Inches Per Minute
Inches per minute (ipm) is a unit of speed that measures how fast something is moving in terms of inches per unit of time. It is commonly used in machining applications, such as when describing the feed rate of a milling machine or a drill bit. The feed rate is the distance that the tool moves along the workpiece in one minute.
One inch per minute is equal to 0.00042333333333333 meters per second, or 0.0254 meters per minute. It can also be converted to other units of speed, such as feet per minute, miles per hour, or kilometers per hour, by using appropriate conversion factors.
How to Convert Inches Per Minute
To convert inches per minute to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert inches per minute to feet per minute, we need to multiply by 12, since there are 12 inches in one foot. To convert inches per minute to miles per hour, we need to multiply by 0.056818181818182, since there are 0.056818181818182 miles in one inch.
Here are some examples of how to convert inches per minute to other units of length in the US Standard system and the SI system:
Where Inches Per Minute Are Used
Inches per minute are mainly used in the United States and other countries that use the US Standard system of measurement. They are often used in machining applications, such as milling, drilling, turning, and cutting, where the feed rate of the tool is an important parameter that affects the quality and efficiency of the process.
For example, a milling machine may have a feed rate of 100 ipm, which means that the tool moves along the workpiece at a speed of 100 inches per minute. A drill bit may have a feed rate of 20 ipm, which means that it advances into the material at a speed of 20 inches per minute.
Inches per minute are also used in some other fields, such as woodworking, printing, sewing, and conveyor belts, where the speed of movement is measured in inches per unit of time.
History of Inches Per Minute
The origin of inches per minute as a unit of speed can be traced back to the development of machining tools and techniques in the Industrial Revolution. As machines became more advanced and precise, there was a need for a standard unit of measurement that could describe the speed and feed rate of the tools.
Inches per minute were chosen as a convenient and simple unit that could be easily calculated and adjusted based on the size and type of the tool and the material being worked on. Inches were already a common unit of length in the US Standard system, so they were easy to apply and understand.
Inches per minute have been used ever since as a standard unit of speed for machining applications in the United States and other countries that use the US Standard system. They have also been adopted by some other fields that involve movement in inches per unit of time.
