Pressure is the force applied per unit area and is widely used in various fields such as engineering, meteorology, and physics. Different units are used globally, making conversions essential for accuracy.
Common Pressure Units
Some widely used pressure units include:
Pascal (Pa): The SI unit of pressure.
Bar (bar): 1 bar = 100,000 Pascals.
Atmosphere (atm): 1 atm = 101,325 Pascals.
Pound per Square Inch (PSI): 1 PSI = 6,894.76 Pascals.
Millimeter of Mercury (mmHg): 1 mmHg = 133.322 Pascals.
Torr (Torr): 1 Torr = 1 mmHg.
