Millimeters per Hour Unit | All you need to know
Millimeters per hour (millimeter/hour, mm/h,mm/hr) measures speed as the distance of one millimeter covered in one hour. Precipitation rates in meteorology are often expressed in millimeters per hour, representing rainfall intensity. Measuring extremely slow processes like water seepage through soil or chemical reactions progressing at negligible rates may use millimeters per hour. The unit provides precision for imperceptibly slow phenomena. Learn more about millimeters per hour.
