Convert mile/hour to millimeter/second
Please provide values below to convert mile/hour [mi/h] to millimeter/second [mm/s], or Convert millimeter/second to mile/hour.
1 mi/h = 447.04 mm/s. To convert mile/hour to millimeter/second, multiply the value by 447.04; to go the other way, divide by it (1 mm/s = 0.00223693629205 mi/h). Both units measure speed and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mi/h = 447.04 mm/s
- 1 mm/s = 0.00223693629205 mi/h
- 10 mi/h = 4470.4 mm/s
- 100 mi/h = 44704 mm/s
How to Convert Mile/hour to Millimeter/second
1 mi/h = 447.04 mm/s
Example: convert 15 mi/h to mm/s:
15 mi/h = 15 × 447.04 mm/s = 6705.6 mm/s

Mile/hour
Mile per hour (mi/h) is a unit of speed representing the number of miles traveled in one hour.
History/Origin
The mile per hour has been used primarily in the United States and the United Kingdom for measuring speed, especially in transportation, since the adoption of the imperial system. Its usage dates back to the widespread use of miles as a distance measure before metric standardization.
Current Use
Today, mi/h is commonly used in the United States and some other countries to express vehicle speeds, speed limits, and other transportation-related velocities. It remains a standard unit in contexts where the imperial system is prevalent.
Millimeter/second
Millimeter per second (mm/s) is a unit of speed representing the distance of one millimeter traveled in one second.
History/Origin
The millimeter per second has been used in scientific and engineering contexts to measure small-scale velocities, especially in fields like fluid dynamics and material science, as a standard unit derived from the metric system.
Current Use
Today, mm/s is commonly used in scientific research, engineering, and technical applications to quantify low velocities, such as in microfluidics, biomechanics, and precision manufacturing.
