Formula

bar × 100 = kPa

Example: 1 bar = 100 kPa

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 Kilopascal?

The kilopascal equals 1,000 pascals and is commonly used for tire pressure specifications. A typical passenger car tire is inflated to about 220 to 250 kPa. Some blood pressure monitors also display readings in kilopascals. In industry, gas pipeline pressures and hydraulic system pressures may be expressed in kPa. Standard atmospheric pressure is approximately 101.325 kPa.
