What is Pressure?
Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.
What is Inch of mercury?
The inch of mercury (symbol: inHg) is a non-SI unit of pressure based on the height of a mercury column one inch high under standard gravity. It is widely used in aviation, meteorology, and vacuum measurement, particularly in the United States and Canada. Although the pascal is the SI unit of pressure, the inch of mercury remains an important unit in many industries. More information is available in the inch of mercury reference.
One inch of mercury is equal to 3,386.39 pascals, 3.38639 kilopascals, 0.0338639 bar, 0.491154 psi, and 25.4 millimeters of mercury. The inch of mercury is commonly used for barometric pressure and vacuum measurements.
What is Centimeter of water?
The centimeter of water (symbol: cmH₂O) is a non-SI unit of pressure defined as the pressure exerted by a one-centimeter column of water under standard gravity. It is widely used in medical equipment, ventilation systems, HVAC engineering, and fluid mechanics because it provides a practical scale for measuring relatively low pressures. The unit is derived from the hydrostatic pressure of water and is described alongside other pressure units in the centimeter of water reference.
One centimeter of water is equal to 98.0665 pascals, 10 millimeters of water, 0.000980665 bar, 0.0142233 psi, and 0.000967841 standard atmosphere. The centimeter of water is commonly used whenever accurate measurement of low pressure is required.
