Convert Inches Per Second to Feet Per Minute (in/s to ft/min) ▶
How to convert
1 foot per minute (ft/min) = 0.2 inch per second (in/s). Foot Per Minute (ft/min) is a unit of Speed used in Standard system. Inch Per Second (in/s) is a unit of Speed used in Standard system. Foot per minute also can be marked as foot/minute.
Inches per second: A unit of speed
Inches 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 second
Inches 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 used
Inches 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 cross-sectional area of the pipe or the nozzle.
Definition of inches per second
According 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 second
The 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 eighty-six 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 units
Here 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
