What Does “Rain MM” Mean in Weather Reports?
When meteorologists report rainfall, they use millimeters (mm) as the standard unit of measurement. But what exactly does rain mm meaning signify? Essentially, 1 mm of rain equals one liter of water per square meter. This measurement helps quantify precipitation accurately, whether it’s a light drizzle or a heavy downpour.
