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.

Technical Atmosphere (at): Engineering Applications

The Technical Atmosphere (at) is a unit of pressure defined as 98,066.5 Pascals. It is based on the pressure exerted by a kilogram-force per square centimeter. Although largely obsolete, the technical atmosphere was historically used in engineering contexts, particularly in Europe, to measure pressures in hydraulic and pneumatic systems.
