About these units
Mile/Hour (mi/h)
The mile per hour represents the number of miles traveled in one hour and is commonly used in the United States, the UK (in road contexts), and several other countries with legacy imperial systems. mph is deeply woven into cultural habits: driver training, speed limits, vehicular performance, and even athletic achievements are often expressed in miles per hour. In science and engineering, however, mph is rarely used because the mile and hour are not SI units. Still, mph retains strong emotional and historical associations—for example, the significance of a car "breaking 200 mph" or the legendary "88 mph" in popular culture. It persists because measurement units often survive long after their historical origins fade.
Millimeter/Minute (mm/min)
A millimeter per minute is a slow mechanical speed often encountered in CNC machining, automated laboratory equipment, and controlled industrial processes. In medicine, infusion pumps, surgical robotics, and controlled incisions may specify movement in mm/min to maintain safety and precision. By using millimeters instead of centimeters or meters, the unit ensures fine control in delicate operations where even small deviations matter.
