What Does Rain mm Mean? When you check the weather forecast, you often see rainfall measured in millimeters (mm). But what does rain mm meaning actually refer to? In simple terms, it represents the depth of rainwater that would accumulate on a flat surface if none of it evaporated, drained, or was absorbed. This standardized unit helps meteorologists and the public understand precipitation levels accurately and consistently. How Precipitation Measurement Works Meteorological stations use rain gauges to collect and measure rainfall. One millimeter of measured rain equates to one liter of water per square meter. This precise method allows for reliable data collection, essential for agriculture, water resource management, and…

What Does Rain mm Mean? When you hear weather forecasts mentioning rainfall in millimeters (mm), it refers to the depth of rainwater collected on a flat surface. This standardized precipitation measurement helps compare data globally. For example, 1 mm of rain equals 1 liter of water per square meter.
