Compare metric and imperial pressure measurement on one interactive scale.
Bar is a metric unit of pressure commonly used in engineering, weather forecasting, hydraulics, and industrial applications. One bar equals 100,000 pascals (100 kilopascals), making it close to atmospheric pressure at sea level. Bar is not an SI unit, but it is widely used alongside SI units such as the pascal and megapascal.
PSI means pounds per square inch. It is an imperial pressure unit that describes one pound-force applied over one square inch of area. PSI is widely used in the United States for tire pressure, gas cylinders, plumbing, pressure gauges, and air compressors.
Pressure values are expressed in different units around the world. A bar-to-PSI conversion lets you compare a metric specification with an imperial gauge or manual accurately.
Gauge pressure and absolute pressure describe different reference points. Converting the unit does not change that reference: barg converts to psig, while bar absolute converts to psia.

Helpful answers about bar-to-PSI pressure conversion.
1 bar equals 14.5038 PSI when rounded to four decimal places.
Multiply the pressure value in bar by 14.5037738.
0.5 bar equals 7.2519 PSI. Multiply 0.5 by 14.5037738 to get the result.
0.6 bar equals 8.7023 PSI. Multiply 0.6 by 14.5037738 to get the result.
1 kgf/cm² equals 0.0980665 MPa. In pressure searches, “1 kg to MPa” normally refers to kilogram-force per square centimetre, not kilogram mass.
0.5 MPa equals approximately 5.0986 kgf/cm².
PSI is commonly used in the United States, while bar is widely used in Europe and many other countries.
Yes. One bar represents approximately 14.5 PSI, so one bar is a larger unit than one PSI.
Many passenger vehicles use approximately 2.0 to 2.5 bar, but always follow the pressure specified by the vehicle manufacturer.
Yes. You can enter positive whole numbers or decimal values.
Yes. It uses the conversion factor 1 bar = 14.5037738 PSI and displays results to practical precision.
Yes. The calculator is responsive and works on phones, tablets, and desktop computers.
