How to convert to BAR
Bar is the metric unit of pressure used in engineering, meteorology, and industrial applications. One bar is approximately equal to standard atmospheric pressure at sea level (1 atm = 1.01325 bar). Pressure measurements in PSI, kPa, MPa, mmHg, and atm can all be converted to bar.
Select the input pressure unit and enter a value to get the bar equivalent. Bar is widely used in Europe for tire pressure, hydraulic systems, and process engineering, making conversions from PSI or kPa a common need.

Frequently asked questions
How many PSI is 1 bar?
1 bar equals approximately 14.504 PSI (pounds per square inch).
How many bar is standard atmospheric pressure?
Standard atmospheric pressure is 1.01325 bar. This is often rounded to 1 bar for practical purposes.
What is the typical tire pressure in bar?
Car tire pressure is usually between 2.0 and 2.5 bar (roughly 29 to 36 PSI). Bicycle tires range from around 2 bar for mountain bikes up to 9 bar for road bike tires.
How does bar relate to kPa?
1 bar equals exactly 100 kPa (kilopascals). The millibar (mbar) used in weather forecasting equals 0.1 kPa.
What is the difference between bar and mbar?
A millibar (mbar) is one thousandth of a bar (1 mbar = 0.001 bar). Meteorologists commonly use millibars or hectopascals (hPa), where 1 hPa = 1 mbar.
