What Does “mm of Rain” Mean?
When you hear weather reports mentioning mm of rain meaning, it refers to millimeters of rainfall. This unit measures the depth of rainwater collected on a flat surface, providing a standardized way to quantify precipitation.
How Rainfall Measurement Works
Meteorologists use rain gauges to measure precipitation in millimeters. One millimeter of rain equals one liter of water per square meter, helping assess water impact and distribution.
Understanding Rainfall Intensity
Light rain is under 2.5 mm/h, moderate up to 7.6 mm/h, and heavy exceeds this. Accurate measurement aids in flood forecasting and agriculture planning.
