Convert Pascals to Bar
Pascals to bar is the conversion you need when a pressure reading is in pascals but the gauge, spec sheet, or industry you're working in speaks in bar. One pascal is exactly 0.00001 bar — a bar is exactly 100,000 pascals — so the number gets much smaller when you switch from pascals to bar.

The formula
To convert pascals to bar, multiply the pressure in pascals by 0.00001 (the same as dividing by 100,000):
bar = pascals × 0.00001
A worked example
Say you're converting 100,000 Pa into bar:
100,000 × 0.00001 = 1 bar
So 100,000 pascals is exactly 1 bar.
Why the number is exact
The bar is defined as exactly 100,000 pascals — a round number chosen to sit close to average air pressure at sea level. Because that definition is exact, one pascal is exactly 0.00001 bar, or one hundred-thousandth of a bar, with nothing rounded away.
When you'll use it
Reading pressure gauges in diving, brewing, and many industrial systems, checking equipment rated in bar, and comparing pressures against roughly one bar of everyday air pressure.
Frequently asked questions
How many pascals are in a bar?
Exactly 100,000 pascals. The bar is defined as exactly 100,000 Pa, which is close to average sea-level air pressure but set as a round, exact number.
Is a bar the same as an atmosphere?
Almost, but not quite. A bar is exactly 100,000 Pa, while a standard atmosphere is exactly 101,325 Pa — so one atmosphere is a little more than one bar.
Is the pascals to bar conversion exact?
Yes. A bar is defined as exactly 100,000 pascals, so one pascal is exactly 0.00001 bar — nothing is rounded.
