Convert Bar to Pascal

One bar equals 100,000 Pa. This converter allows you to easily convert between Bar and Pascal in real time.

Formula

bar × 100,000 = Pa

Example: 1 bar = 100,000 Pa

What is Bar?

The bar is a unit of pressure equal to 100,000 pascals, which is very close to standard atmospheric pressure (101,325 Pa). This convenient relationship makes it widely used in industry. Scuba tank pressure is typically around 200 bar, espresso machines extract at about 9 bar, and fire extinguishers are pressurized to several bar. While not an SI unit, the bar is accepted for use with the SI in many countries.

What is Pascal?

The pascal is the SI unit of pressure, defined as one newton of force per square meter. Named after French mathematician and physicist Blaise Pascal, it is the foundation for related units like the hectopascal used in weather reports. Since one pascal is a very small amount of pressure, practical applications typically use kilopascals (kPa) or megapascals (MPa). In materials engineering, stress and tensile strength are expressed in megapascals or gigapascals.
