Convert Pascal to Bar
Convert Pascals to Bar for industrial, diving, and meteorology uses with the exact 100,000:1 relationship.
How to Convert Pascal to Bar
To convert Pascal to Bar, divide Pascals by 100,000 because 1 bar = 100,000 Pa.
Conversion Formula:
value / 100000Understanding the Conversion
Pascal to Bar is a common step when industrial specs, process equipment, or diving gauges use bar instead of Pascals. Because 1 bar is exactly 100,000 Pa, dividing by 100,000 converts Pascals to bar. Bar values are convenient for medium-to-high pressures where Pa would be unwieldy.
Reference: standard atmosphere is about 1.01325 bar, so converting atmospheric Pascals (101,325 Pa) yields roughly 1.01325 bar. Many compressor and hydraulic ratings use bar, and scuba divers often refer to bar for tank pressures and depth-related calculations. Converting sensor outputs in Pascals to bar keeps reports aligned with these contexts.
The relationship is linear and precise. Multiply bar by 100,000 to return to Pascals. Use bar when communicating with teams that expect that unit while retaining SI accuracy in the background.
Conversion Examples
Example: Convert 250,000 Pa to bar
- Step 1: Divide by 100,000.
- Step 2: 250,000 ÷ 100,000 = 2.5.
- Step 3: Result is 2.5 bar.
250,000 Pa = 2.5 bar
Typical compressor discharge range.
Example: Convert 101,325 Pa to bar
- Step 1: 101,325 ÷ 100,000 = 1.01325.
- Step 2: Result is 1.01325 bar.
- Step 3: Matches atmospheric pressure.
101,325 Pa = 1.01325 bar
Standard atmosphere expressed in bar.
Example: Convert 50,000 Pa to bar
- Step 1: 50,000 ÷ 100,000 = 0.5.
- Step 2: Result is 0.5 bar.
- Step 3: Useful for low/medium process pressure.
50,000 Pa = 0.5 bar
Shows sub-atmospheric to low bar ranges.
Conversion Formula
Bar is a decimal multiple of Pascal. Dividing by 100,000 shifts Pascals into bar, reflecting the 10^5 scaling.

Unit Definitions
Pascal (Pa)
SI pressure unit, one newton per square meter.
1 bar = 100,000 Pa; 1 kPa = 1,000 Pa; 1 psi ≈ 6,894.76 Pa; 1 mbar = 100 Pa.
Bar (bar)
Metric-adjacent pressure unit widely used in industry and diving.
1 bar = 100,000 Pa = 100 kPa ≈ 14.5038 psi ≈ 750.062 Torr ≈ 1,000 mbar.
Common Use Cases
- Industrial process: report sensor data in bar for pumps and pipelines.
- Diving: relate tank pressures and depth calculations in bar.
- Meteorology: compare atmospheric pressure to bar-based references.
- Hydraulics: summarize system pressures where bar is standard.
- QA and audits: align SI readings with bar-centric documentation.
- Education: demonstrate decimal scaling between Pa and bar.
Frequently Asked Questions
Is 1 bar the same as 1 atm?
They are close but not equal. 1 atm ≈ 1.01325 bar. Use bar for convenience; use kPa or Pa for exact SI work.
Why use bar instead of Pa?
Bar yields manageable numbers for medium/high pressures and is common in industrial and diving contexts.
Can I convert bar back to Pa easily?
Yes. Multiply bar by 100,000 to return to Pascals.
