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 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.
What is Centimeter of Mercury?
The centimeter of mercury (symbol: cmHg) is a non-SI unit of pressure based on the pressure exerted by a one-centimeter column of mercury under standard gravity. It has traditionally been used in scientific instruments, laboratory measurements, and vacuum systems. Although the pascal is the SI unit of pressure, the centimeter of mercury is still encountered in specialized applications. It is closely related to the Torr and other mercury-based pressure units.
One centimeter of mercury is equal to 1,333.22 pascals, 10 millimeters of mercury, 0.0133322 bar, 0.193367 psi, and 0.0131579 standard atmosphere. This unit remains useful for comparing pressure values in traditional measurement systems.
