Absolute Force. In magnetism, is intensity of Earth's magnetism, or of a magnet's force, expressed in dynes.
Absolute Humidity. Weight of water held in a given volume of atmospheric air. Usually expressed in grammes per cubic metre.
Absolute Pressure.Pressure of a fluid measured above a perfect vacuum. In practical engineering, it is taken as steam pressure plus 15 lbs. Absolute pressure of condenser is taken to be-in barometric inches—half height of barometer minus vacuum reading.
Absolute Temperature. Temperature measured from an Absolute zero at which there is an entire absence of heat. Zero is equivalent to –273 -l°C (-459-58°F). Usually measured in Centigrade units.
