What Does “Rain mm” Mean?
When you hear weather reports mention rainfall in millimeters (mm), it refers to the depth of rainwater collected on a flat surface. One millimeter of rain means one liter of water per square meter. This standard unit helps in comparing and predicting precipitation accurately worldwide.
How Rainfall Measurement Works
Meteorologists use rain gauges to measure precipitation. These devices collect rain over a set period, and the depth is read in millimeters. This method is crucial for agriculture, hydrology, and daily weather forecasting.
Why Millimeters Matter
Using millimeters provides precision. Unlike subjective terms like “light” or “heavy” rain, mm offers a universal standard. For instance, 0.2 mm might be a drizzle, while 50 mm could indicate a storm.
