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 Pound Force Per Square Inch?
The pound force per square inch (symbol: psi or lbf/in2) is a non-SI unit of pressure equal to one pound-force applied over an area of one square inch. It is one of the most widely used pressure units in the United States for measuring tire pressure, hydraulic systems, compressed gases, and industrial equipment. Although the pascal is the SI unit of pressure, the psi remains the preferred unit in many engineering applications. More information is available in the pounds per square inch article.
One pound force per square inch is equal to 6,894.76 pascals, 6.89476 kilopascals, 0.0689476 bar, 0.068046 standard atmosphere, and 0.0703069 kilogram-force per square centimetre. The psi is one of the world's most recognized units for measuring pressure.
What is Millibar?
The millibar (symbol: mbar) is a non-SI unit of pressure equal to one-thousandth of a bar or exactly 100 pascals. It has been widely used in meteorology to report atmospheric pressure and remains common in weather forecasts, although the SI unit hectopascal has largely replaced it. One millibar is numerically equal to one hectopascal. More information is available in the bar (unit) reference.
One millibar is equal to 100 pascals, 1 hectopascal, 0.1 kilopascal, 0.001 bar, and 0.000986923 standard atmosphere. The millibar remains a familiar unit for atmospheric pressure worldwide.
