Air conditioning (often referred to as AC, A/C, or air con) is the process of removing heat and moisture from the interior of an occupied space, to improve the comfort of occupants.
An aircraft is a machine that is able to fly by gaining support from the air.
An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level.
American open-wheel car racing, also known as Indy Car racing, is a category of professional-level automobile racing in the United States and North America.
Atmospheric pressure, sometimes also called barometric pressure, is the pressure within the atmosphere of Earth (or that of another planet).
Aviation, or air transport, refers to the activities surrounding mechanical flight and the aircraft industry.
The bar is a metric unit of pressure, but is not approved as part of the International System of Units (SI).
A barometer is a scientific instrument used in meteorology to measure atmospheric pressure.
Champ Car is the general name for a class and specification of American professional top-level open wheel cars used in American open-wheel car racing for many decades, associated primarily with the Indianapolis 500.
A constant-speed propeller is a variable-pitch aircraft propeller that automatically changes its blade pitch in order to maintain a chosen rotational speed.
In aviation and aviation meteorology, a flight level (FL) is defined as a vertical altitude at standard pressure, nominally expressed in hundreds of feet.
Manifold vacuum, or engine vacuum in an internal combustion engine is the difference in air pressure between the engine's intake manifold and Earth's atmosphere.
Mercury is a chemical element with symbol Hg and atomic number 80.
The National Institute of Standards and Technology (NIST) is one of the oldest physical science laboratories in the United States.
The pascal (symbol: Pa) is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength.
The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units.
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
A reciprocating engine, also often known as a piston engine, is typically a heat engine (although there are also pneumatic and hydraulic reciprocating engines) that uses one or more reciprocating pistons to convert pressure into a rotating motion.
Refrigeration is a process of removing heat from a low-temperature reservoir and transferring it to a high-temperature reservoir.
The standard acceleration due to gravity (or standard acceleration of free fall), sometimes abbreviated as standard gravity, usually denoted by or, is the nominal gravitational acceleration of an object in a vacuum near the surface of the Earth.
The torr (symbol: Torr) is a unit of pressure based on an absolute scale, now defined as exactly of a standard atmosphere (101.325 kPa).
A turbocharger, or colloquially turbo, is a turbine-driven forced induction device that increases an internal combustion engine's efficiency and power output by forcing extra air into the combustion chamber.
A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
The United States Auto Club (USAC) is one of the sanctioning bodies of auto racing in the United States.
United States customary units are a system of measurements commonly used in the United States.
The vacuum brake is a braking system employed on trains and introduced in the mid-1860s.
Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time.
