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.
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.
