1 Pa equals 1E-5 bar. To convert Pa to bar, multiply the value by 1E-5; divide by 1E-5 to convert back. Enter any number above and the result appears instantly — free and entirely in your browser.
How do you convert Pa to bar?
The conversion formula is bar = Pa × 1E-5. The conversion factor is fixed by definition, so the result is always exact.

What is Pa (Pa)?
The pascal (Pa) is the SI unit of pressure: one newton per square metre. It is small for everyday use, so multiples like kPa, bar and MPa are far more common.
What is bar (bar)?
The bar is a metric pressure unit equal to exactly 100,000 pascals — very close to average air pressure at sea level. It is widely used across Europe for tyre pressure, weather reports and industrial systems.
Why convert Pa to bar?
Pressure units differ by region and field: Europe uses bar, the US uses psi, science uses pascals and kilopascals, and medicine still uses mmHg. Converting between them is a daily need for mechanics, engineers and divers.
Standard atmospheric pressure is defined as exactly 101,325 Pa — equal to 1.01325 bar or 14.696 psi (BIPM/NIST). Car tyres are typically inflated to about 2.2–2.5 bar (32–36 psi).
