In 1 pascals there are 0.0000100000 bars. Meanwhile in 1 bars there are 100,000 pascals. Keep reading to learn more about each unit of measure and how they are calculated. Or just use the Bars to Pascals calculator above to convert any number.

To convert pascals (Pa) to bars (bar), use this fixed pressure relation: 1 bar = 100,000 Pa. That means a bar is much larger than a pascal.
Conversion formula (Pa to bar):
Quick examples:
Tip: If you need a fast mental check, move the decimal 5 places left when converting Pa to bar.
A pascal is the SI unit of pressure. It equals one newton per square meter (N/m²). A bar is a common metric pressure unit used in weather, engineering, and compressed gas work. Bar is larger than a pascal, so you’ll often see big Pa values and smaller bar values for the same pressure.
Use this conversion:
This works because 1 bar = 100,000 Pa.
1 Pa = 0.00001 bar (that’s 1 × 10⁻⁵ bar).
Pascals are much smaller than bars, so the bar value is often a small decimal.
1 bar = 100,000 Pa.
This is the key value used for any Pa to bar conversion.
To convert Pa to bar, move the decimal 5 places to the left.
Example: 250,000 Pa = 2.5 bar.
Kilopascals are common in tire pressure and HVAC.
Example: 220 kPa = 2.2 bar.
Megapascals show up in hydraulics and material specs.
Example: 0.8 MPa = 8 bar.
Here are a few quick reference values:
Not exactly. Standard atmospheric pressure is close to one bar, but not equal.
A pascal is a small unit. Many real-world pressures are tens of thousands of pascals. Bars compress that into a simpler number. For example, 250,000 Pa reads more clearly as 2.5 bar.
Use pascals (Pa) when you need SI units or fine detail, like lab work and physics. Use bars (bar) for many practical pressure readings, like compressed air systems, pumps, and weather charts.
No. The unit conversion between pascals and bars never changes. Temperature can change the pressure in a system, but it doesn’t change how Pa converts to bar.
It depends on your use.
The Calculate Box tool to convert pascals to bars uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a pascals value in the box and have it instantly converted to bars.
