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 Torr?
Torr (symbol: Torr) is a unit of pressure defined as exactly 133.322368421 pascals, equivalent to one millimeter of mercury (mmHg) under standard conditions. The torr is widely used in vacuum technology, physics, analytical chemistry, and medical applications to measure low-pressure environments. It is commonly used to specify vacuum pump performance, laboratory vacuum systems, and pressure in scientific instruments. Torr is frequently converted to pascals, millimeters of mercury (mmHg), and standard atmospheres (atm) for engineering, laboratory, and industrial pressure measurements.
