Pounds per square inch The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in 2; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 N/m 2. Pounds per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around 14.7 psi, this will be added to any pressure reading made in air at sea level.

psi â Pounds per Square Inch Pressure Unit psi – Pounds per Square Inch Pressure Unit Pounds or pound force per square inch (psi, lb/in², pfsi or lbf/in²) is a widely used British and American unit of measure for pressure. 1 psi equals 6,894.76 pascals. In the USA the PSI pressure unit is the pimary unit of measure for pressure and almost all pressure instruments are specified and display in pounds per square inch. The psi is still used extensively in the UK but the bar pressure unit has mostly replaced it as the primary pressure unit.

What is the meaning of PSI? When the total pressure is considered, as in chemical analysis and in thermodynamics it is often referred to as psia or absolute pressure of the substance or of the fluid which would then include the atmospheric pressure. It is important to include the subscript g or a to define which pressure is being noted. Psi can also be the difference between two pressures, be they gage or absolute. Psi is also used in materials engineering referring to the unit stress caused when a load is imposed on a structure or on a part.

Psi (letter) Psi is the 23rd letter of the Greek alphabet and has a numeric value of 700. In both Classical and Modern Greek, the letter indicates the combination /ps/. For Greek loanwords in Latin and modern languages with Latin alphabets, psi is usually transliterated as ps. In English, the letter is pronounced /saɪ/ or sometimes /psaɪ/. The letter's origin is uncertain. It may or may not derive from the Phoenician alphabet. It appears in the 7th century BC, expressing /ps/ in the Eastern alphabets ...

What's different between psi,psia and psig? Trending Now. Answers. Best Answer: psia is pounds per square inch absolute, that is it includes atmospheric pressure. psig is the reading you get on a gauge and is atmospheric pressure (14.7 psi) less. psi is just pounds per square inch and it is appropriate to use this when one is talking about pressure difference.
