psi pressure


0.45359237 P

As the pascal is very small unit, relative to industrial pressures, the kilopascal is commonly used. This is because PSI as measured by PSI gauge (PSIG) is inherently measured as a differential balance against atmospheric pressure, generally being immersed in it. Multiples of atmospheric pressure (ATM) = 6.8046 xPSI.


A vessel completely void of any air molecules (at sea level) would be roughly -14.7 PSIG, and ambient air pressure is always measured as 0 PSIG, regardless of whatever current barometric pressure is. Torr, the measurement used by the inventor of the barometer = 51.71493 PSI. 2

Why it’s important to measure barometric pressure accurately.

Copyright 1999 - 2020, TechTarget The converse is pounds per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. The megapound per square inch (Mpsi) is another multiple equal to a million psi. The pressure of a vessel completely void of any air molecules would be 0 PSIA, while average atmospheric surface pressure (at sea level) is roughly 14.7 PSIA.

It is used in mechanics for the elastic modulus of materials, especially for metals.[5].

For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psia) will have a pressure of 79.7 psia (14.7 psi + 65 psi). Cookie Preferences

They are mostly used in materials science, where the tensile strength of a material is measured as a large number of psi.[4]. In fluid pressure measurement, the use of PSI is generally relative to atmosphere.


kg in 1 PSI = 0.068046 atmospheres; 0.0689476 Bar; 6894.76 Pascals; 51.7149 Torr; 2.03602 inHg; 27.7076 inches of water column PSIA - PSI Absolute.


Risk assessment is the identification of hazards that could negatively impact an organization's ability to conduct business. Choosing the right pressure transducer just got easier. m In pneumatic and hydraulic pressure, PSI expresses the force exerted on its containing vessel by the two relative fluids. 0.45359237 Submit your e-mail address below.


Absolute pressure is measured relative to a full vacuum.

Copyright © 2020 Setra Systems. Gauge pressure is measured relative to ambient atmospheric pressure. ( Approximate conversions (rounded to some arbitrary number of digits, except when denoted by "≡") are shown in the following table. 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 (PSI) is a measurement of pressure in the Imperial system of measurement. m Topics:

× Most industrial applications measure gauge pressure, including engine test stands which measure oil, fuel line, and coolant pressure on OEM prototypes for cars, trucks, construction equipment, and airplanes. s The pressure of a vessel completely void of any air molecules would be 0 PSIA, while average atmospheric surface pressure (at sea level) is roughly 14.7 PSIA. )

Obviously, a higher PSI rating equals more power, whereas a lower PSI rating equals a lower maximum amount of pressure output.

The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in2;[1] abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units.

Absolute pressure is measured relative to a full vacuum.   Gauges measuring pressure are used in all manner of instrumentation for vehicles, pneumatic and hydraulic machines, as well as industrial and safety systems. PSI measurement may also be absolute: relative to a vacuum or PSI absolute (PSIA). Bar, a rounding off of atmosphere based on 100 000 Pa = 6.8948 x PSI. Low-Pressure Gauges for Chemicals Use in low-pressure applications up to 160 psi. Pa 2 The kilopound per square inch (ksi) is a scaled unit derived from psi, equivalent to a thousand psi (1000 lbf/in2). kg

This guide makes finding the exact right solution for your application simple and easy! ksi are not widely used for gas pressures. [2][3] When gauge pressure is referenced to something other than ambient atmospheric pressure, then the units would be pounds per square inch differential (psid).

In compressed air power, a PSI gauge is the equivalent to a fuel gauge. Technical atmospheres: 1 kilogram of force per centimeter squared (AT) = 7.03069 x PSI. Do Not Sell My Personal Info.

The conversion in SI units is 1 Mpsi = 6.895 GPa, or 1 GPa = 0.145 Mpsi.
