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 Millimeter of Mercury?
The millimeter of mercury (symbol: mmHg) is a non-SI unit of pressure based on the pressure exerted by a one-millimeter column of mercury under standard gravity. It is widely used in medicine, physiology, meteorology, and vacuum technology. Blood pressure is commonly measured in millimeters of mercury, making it one of the world's best-known pressure units. The unit is closely related to the Torr.
One millimeter of mercury is equal to 133.322 pascals, 0.133322 kilopascals, 0.00133322 bar, 0.0193368 pounds per square inch, and 0.00131579 standard atmosphere. The millimeter of mercury remains the standard unit for blood pressure measurements.
What is Inch of water?
The inch of water (symbol: inH₂O or inH2O) is a non-SI unit of pressure based on the pressure exerted by a one-inch column of water under standard gravity. It is commonly used in HVAC systems, ventilation, gas distribution, and fluid mechanics to measure low-pressure differences. Although the pascal is the SI unit of pressure, the inch of water remains widely used because it provides a convenient scale for low-pressure applications. More information is available in the inch of water reference.
One inch of water is equal to 249.089 pascals, 2.54 centimeters of water, 0.00249089 bar, 0.0361263 psi, and 0.249089 kilopascals. The inch of water is one of the most commonly used units for measuring low gas and air pressures.
