Unit Information
Pascal (Pa)
Definition: The SI unit of pressure, equal to one newton per square meter.
History: Named after French mathematician Blaise Pascal.
Current Use: Standard unit for pressure in scientific applications.
Kilopascal (kPa)
Definition: A unit of pressure equal to 1000 pascals.
History: Commonly used for practical pressure measurements.
Current Use: Used for tire pressure, weather, and engineering.
Megapascal (MPa)
Definition: A unit of pressure equal to 1,000,000 pascals.
History: Derived from the pascal, used for very high pressure measurements.
Current Use: Common in high-pressure systems like hydraulics and aerospace.
Bar (bar)
Definition: A unit of pressure equal to 100,000 pascals.
History: From Greek word "baros" meaning weight.
Current Use: Widely used in meteorology and engineering.
Millibar (mbar)
Definition: A unit of pressure equal to one thousandth of a bar, or 100 pascals.
History: Historically used in meteorology and closely related to the hectopascal.
Current Use: Still seen in legacy weather reports; hPa is preferred today.
Pound per Square Inch (psi)
Definition: A unit of pressure equal to one pound-force per square inch.
History: Traditional imperial unit.
Current Use: Commonly used in the US for tire and gas pressure.
Standard Atmosphere (atm)
Definition: A unit of pressure equal to 101,325 pascals.
History: Based on average atmospheric pressure at sea level.
Current Use: Used as a reference pressure in various applications.
Torr (Torr)
Definition: A unit of pressure equal to 1/760 of a standard atmosphere.
History: Named after Italian physicist Evangelista Torricelli.
Current Use: Used in vacuum technology and medicine.
Hectopascal (hPa)
Definition: A unit of pressure equal to 100 pascals.
History: Common in meteorology as a direct SI alternative to millibar (1 hPa = 1 mbar).
Current Use: Standard for atmospheric pressure in weather reports.
Pound-force inch pressure (lbf/in)
Definition: A unit of pressure based on force per inch.
History: Used in engineering and hydraulics.
Current Use: Found in some engineering applications.
