Description

Millimeter of Water (mmH₂O): Low-Pressure Measurements

The Millimeter of Water (mmH₂O) is a unit of pressure equal to the pressure exerted by a column of water one millimeter high. It is approximately equal to 9.80665 Pascals. This unit is used in various applications requiring the measurement of small pressure differences, such as in ventilation systems and laboratory experiments.

Hectopascal (hPa): A Meteorological Standard

The Hectopascal (hPa) is a unit of pressure equal to 100 Pascals. It is commonly used in meteorology to report atmospheric pressure. Since 1 hPa equals 1 millibar, it serves as a direct replacement in weather reports and forecasts. Atmospheric pressure at sea level is typically around 1013 hPa, and variations in this value are crucial for weather prediction.
