![]() ![]() Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types. You can find metric conversion tables for SI units, as well as English units, currency, and other data. Thus a reading of 30 psig on a tire gauge represents an absolute pressure of 44.7 psi.Ĭ provides an online conversion calculator for all types of measurement units. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. 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. 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. Using the conversion formula above, you will get: Value in psi 3.7 × 14.503773800722 53.664 pounds per square inch. This point of conversion is multiplication by 14.504. Suppose you want to convert 3.7 bar into pounds per square inch. This can be done by finding their mutual point of conversion. Using the conversion formula above, you will get: Value in psi 2.7 × 14.503773800722 39. ![]() 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). Here is the formula: Value in pounds per square inch value in bar × 14.503773800722. Suppose you want to convert 2.7 bar into pounds per square inch. bar to kilogram-force/square millimeter.You can do the reverse unit conversion from
