Description

Standard Atmosphere (atm): A Reference Pressure

The Standard Atmosphere (atm) is a unit of pressure defined as 101,325 Pascals. It represents the average atmospheric pressure at sea level and is used as a reference point in various scientific calculations. The atm is particularly useful in chemistry and physics for standardizing measurements involving gases and reactions under 'standard' conditions.

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.
