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.
