Pascal (Pa)
Definition: Pascal (Pa) is the base unit of Pressure in the International System of Units (SI).
History/origin: The pascal is the fundamental unit of Pressure in the International System of Units.
Current use: The pascal is used worldwide for scientific, engineering, and everyday measurements.
Kilopascal (kPa)
Definition: Kilopascal (kPa) is a metric prefix multiple of the Pascal (Pa). 1 kPa = 1,000 Pa.
History/origin: The prefix "kPa" was adopted as part of the metric system to denote multiples and submultiples of base units.
Current use: It is widely used in countries that have adopted the metric system.
Bar (bar)
Definition: Bar (bar) is a unit of Pressure. 1 bar = 100,000 Pa
History/origin: The bar is used in various scientific and engineering applications.
Current use: It is commonly used in various fields including science, engineering, and everyday measurements.
Pound-force per square inch (psi)
Definition: Pound-force per square inch (psi) is a unit of Pressure. 1 psi = 6,894.757293168 Pa
History/origin: The pound-force per square inch has been historically used in the imperial and US customary measurement systems.
Current use: It is primarily used in the United States and a few other countries.
Standard Atmosphere (atm)
Definition: Standard Atmosphere (atm) is a unit of Pressure. 1 atm = 101,325 Pa
History/origin: The standard atmosphere was originally defined as the pressure exerted by a column of mercury 760 mm high at 0°C under standard gravity. It is widely used as a reference pressure in scientific and engineering contexts.
Current use: It is commonly used in various fields including science, engineering, and everyday measurements.
Torr (Torr)
Definition: Torr (Torr) is a unit of Pressure. 1 Torr = 133.3223684211 Pa
History/origin: The torr was named after Evangelista Torricelli and is defined as 1/760 of a standard atmosphere. It is primarily used in vacuum physics and scientific applications.
Current use: It is commonly used in various fields including science, engineering, and everyday measurements.
