![]() 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. As you descend into the water, which is much denser than the atmosphere, you accumulate atmospheric pressure more quickly. The bar is a metric unit of pressure, but not part of the International System of Units (SI) it is defined as 100,000 Pa (100 kPa). As a result, it is much easier to measure atmospheric pressure in Bars than PSI, which is around 14.7 PSI to 1 ATM. 1 ATM is roughly equivalent to 1 Bar: 1.013 bar 1 ATM. By contrast, psia measures pressure relative to a vacuum (such as that in space). This is known as 1 atmosphere (or ATM) of pressure. Current use: The psi is fairly widely used to measure numerous pressures, such as tire pressure, scuba tank pressure, natural gas pipeline pressure, among others. 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. Inflation pressures for older models can usually be found either on one of the. 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). Psig to bar, or enter any two units below: Enter two units to convert From: Type in unit symbols, abbreviations, or full names for units of length, area, mass, pressure, and other types.You can do the reverse unit conversion from It is the pressure resulting from a force of one pound-force applied to an area of one square inch.Ĭ provides an online conversion calculator for all types of measurement units. Choose a value between 0 and 3.5 bar from the car tyre pressure conversion table below, to obtain the converted value in psi. The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/in² or lbf/in²) is a unit of pressure or of stress based on avoirdupois units. Enter a car tyre pressure in bar below to convert it to the equivalent car tyre pressure in psi. The word bar is of Greek origin, báros meaning weight. The pressure unit bar can be converted into pounds force per square inch in the following way: 1 psi 6,894.76 pascals (Pa) 1 bar 100,000 pascals (Pa) psi value x 6,894.76 Pa bar value x 100,000 Pa psi value bar value x 14. 1 pascal is equal to 0.01 millibar, or 0.00014503773800722 psi. Answer: 0.06894757 bar Divide by 14.5 for quick conversions lb/in 2 / 14.5 bar Solution To convert lb/in 2 to bar, use the conversion factor 1 bar 14. Psi is a pressure unit and equals to the force of one pound applied to one square inch. We assume you are converting between millibar and pound/square inch.You can view more details on each measurement unit: millibar or psi The SI derived unit for pressure is the pascal. How many millibar in 1 psi The answer is 68.9475728. Psi to bars, or enter any two units below: Enter two units to convert From: More information from the unit converter. The value will be converted to all other units of the actual measure. Simply select the input unit, enter the value and click 'Convert' button. This is simple to use online converter of weights and measures. You can do the reverse unit conversion from foot) The pressure value 1.1 bar in words is 'one point one bar'.
