Symbols, abbreviations, or full names for units of length,Īrea, mass, pressure, and other types. You can find metric conversion tables for SI units, as wellĪs English units, currency, and other data. 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. Its official symbol is "bar" the earlier "b" is now deprecated, but still often seen especially as "mb" rather than the proper "mbar" for millibars. The word bar is of Greek origin, báros meaning weight. The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). It is widely used in the daily life particularly in European countries, though that is a non-SI unit. Same day shipment with global shipping options. Psia to bar, or enter any two units below: Enter two units to convert From: 50.76321 Psi (Psi) Bar : The bar is a unit of measurement for pressure. Buy a -1.3 Bar (-15.44 psi) Pressure Gauge Below Plastic/Brass 63 mm Class 2.5 online from Tameson today. Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi.Ĭonversion calculator for all types of measurement units. So, to convert directly from bar to pounds per square inch, you multiply by 14.503774. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. For example, to convert from bar to pounds per square inch you would multiply by 100000 then divide by 6894.757. The head in feet water column can be calculated from pressure 100 psi with eq. Example - Converting Pressure - psi - to Pump Head - feet. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. The pressure - psi - of a water pump operating with head 120 ft can be calculated with eq.
At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. By contrast, psia measures pressure relative to a vacuum (such as that in space). Psig (pound-force per square inch gauge) is a unit of pressure relative to the surrounding atmosphere. 1 psi psi 6894.7572931783 pascal Pa psi to pascal, pascal to psi.
