**What Does “Rain MM” Mean? Unraveling the Mystery**

Have you ever glanced at a weather report and wondered, “What does ‘rain mm’ mean?” You’re not alone. This common meteorological term refers to rainfall measured in millimeters, indicating the depth of rainwater collected over a specific area. Understanding rain mm meaning is key to interpreting precipitation data accurately.

**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. This standardized unit helps compare rainfall intensity across regions and seasons.

**Why Millimeters Matter**

Using millimeters provides precision for agriculture, hydrology, and climate studies. Light rain measures under 2.5 mm/hour, while heavy downpours exceed 7.6 mm/hour. Accurate data supports flood warnings and water resource management.

**Frequently Asked Questions**

Is 10 mm of rain a lot?
