Rainfall is measured in millimeters (mm) because this unit provides a clear and precise representation of the depth of water that falls over a specific area. Since rainfall accumulates on surfaces, expressing it in millimeters allows for easy comparison and understanding of precipitation amounts. Additionally, using millimeters helps in calculating water volume and assessing its impact on soil and drainage systems. This standardized measurement is widely used in meteorology and hydrology.
