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 Water?
The millimeter of water (symbol: mmH₂O or mmH2O) is a non-SI unit of pressure defined as the pressure exerted by a one-millimeter column of water under standard gravity. It is commonly used in ventilation systems, clean rooms, HVAC engineering, and laboratory instruments to measure small pressure differences. Although the pascal is the SI unit of pressure, the millimeter of water remains a practical unit for low-pressure applications. It is based on the concept of a water column.
One millimeter of water is equal to 9.80665 pascals, 0.1 centimeter of water, 0.0000980665 bar, 0.00142233 pounds per square inch, and 0.00980665 kilopascal. The millimeter of water is widely used for measuring very low gas and liquid pressures.
What is Kilopascal?
The kilopascal (symbol: kPa) is an SI-derived unit of pressure equal to one thousand (103) pascals. It is one of the most widely used pressure units in engineering, meteorology, automotive systems, construction, and scientific research. The kilopascal provides a practical scale for measuring atmospheric pressure, tire pressure, and fluid pressure. It uses the SI prefix kilo, representing a factor of one thousand.
One kilopascal is equal to 1,000 pascals, 0.01 bar, 0.001 megapascal, 0.145038 psi, and 0.00986923 standard atmosphere. The kilopascal is the preferred SI unit for many everyday and industrial pressure measurements.
