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 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.
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.
