Convert millimeter/hour to Mach (20°C, 1 atm)
Please provide values below to convert millimeter/hour [mm/h] to Mach (20°C, 1 atm) [M], or Convert Mach (20°C, 1 atm) to millimeter/hour.
1 mm/h = 8.0985e-10 M. To convert millimeter/hour to Mach (20°C, 1 atm), multiply the value by 8.0985e-10; to go the other way, divide by it (1 M = 1234799999.01 mm/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 mm/h = 8.0985e-10 M
- 1 M = 1234799999.01 mm/h
- 10 mm/h = 8.09847749271e-09 M

Millimeter/hour
Millimeter per hour (mm/h) is a unit of measurement that indicates the rate of rainfall or precipitation, representing how many millimeters of water fall in one hour.
History/Origin
The millimeter per hour has been used in meteorology and hydrology to quantify rainfall intensity, especially with the advent of precise rain gauges and weather measurement tools in the 20th century.
Current Use
Today, mm/h is commonly used in weather forecasting, climate studies, and hydrological assessments to measure and communicate the intensity of rainfall events.
Mach (20°c, 1 Atm)
Mach is a unit of speed representing the ratio of an object's speed to the speed of sound in the surrounding medium, typically at 20°C and 1 atm pressure.
History/Origin
Named after physicist Ernst Mach, the Mach number was developed in the early 20th century to describe speeds relative to the speed of sound, especially in aeronautics and fluid dynamics.
Current Use
Mach is widely used in aeronautics and astronautics to express aircraft and spacecraft speeds, particularly in high-speed flight and supersonic travel contexts.
Frequently Asked Questions
What is 1 millimeter/hour in Mach (20°C, 1 atm)?
1 millimeter/hour (mm/h) = 8.0985e-10 Mach (20°C, 1 atm) (M).
How do you convert millimeter/hour to Mach (20°C, 1 atm)?
Multiply the millimeter/hour value by 8.0985e-10. For example, 25 mm/h × 8.0985e-10 = 2.02461937318e-08 M.
What is 10 millimeter/hour in Mach (20°C, 1 atm)?
10 mm/h = 8.09847749271e-09 M.
Which unit is larger, the millimeter/hour or the Mach (20°C, 1 atm)?
The Mach (20°C, 1 atm) is the larger unit: 1 mm/h equals only 8.0985e-10 M.
