How Pascal Relates to Bar
About the Pascal
Pascal (Pa) is a unit of pressure measurement. 1 pascal is equal to 0.0000100 bar.
The Bar in Engineering
Bar (bar) is a unit of pressure measurement. 1 bar is equal to 100000.0000000 pascal.
Pressure Units Across Industries
Pressure measurements vary dramatically by industry. Meteorologists report in millibars or hectopascals, tire shops use PSI, scuba divers think in atmospheres or bar, vacuum engineers work in torr, and hydraulic systems specify in megapascals. A single industrial plant might encounter all these units across different equipment manuals, safety datasheets, and regulatory standards from different countries.

How to Convert Pascal to Bar?
We can convert pascal to bar by using an example.
Example:
Convert 20 Pascal to Bar?
We know 1 Pascal = 0.0000100 bar; 1 Bar = 100000.0000000 pascal.
20 pascal = ___bar
20 × 0.0000100 = 0.00020 bar (we know 1 pascal = 0.0000100 bar)
Answer:
20 pascal = 0.00020 bar
How to Convert Pascal to Bar (Step-by-Step)
Converting pascals to bar is needed when translating laboratory instrument readings (SI units) to factory-floor gauges and industrial specifications. The conversion factor is 1 Pa = 0.00001 bar (or 1 Pa = 10⁻⁵ bar).
- Write down the pressure value in pascals (Pa).
- Divide the value by 100,000 (or multiply by 0.00001).
- The result is the equivalent pressure in bar.
- Equivalently, move the decimal point 5 places to the left.
Common Pascal to Bar Conversions
Laboratory and scientific pressures translated to industrial bar gauge readings.
| Pascal | Bar |
|---|---|
| 100 Pa | 0.001 bar |
| 1,000 Pa | 0.01 bar |
| 10,000 Pa | 0.1 bar |
| 50,000 Pa | 0.5 bar |
| 100,000 Pa | 1.0 bar |
| 101,325 Pa | 1.01325 bar |
| 500,000 Pa | 5.0 bar |
| 1,000,000 Pa | 10.0 bar |
Solved Examples: Pascal to Bar
Question 1: A pressure transducer in a lab outputs 345,000 Pa. What should the factory gauge read in bar?
Solution:
Pressure in bar = 345,000 ÷ 100,000
= 3.45 bar
Answer: 345,000 Pa = 3.45 bar — set the factory pressure regulator to 3.5 bar.
Question 2: A materials testing machine applies 2,500,000 Pa to a specimen. Express in bar for the operator.
Solution:
Pressure in bar = 2,500,000 ÷ 100,000
= 25 bar
Answer: 2,500,000 Pa = 25 bar — typical tensile test fixture clamping pressure.
Question 3: A ventilation system shows 250 Pa pressure drop. What is this on a bar-scale gauge?
Solution:
Pressure in bar = 250 ÷ 100,000
= 0.0025 bar
= 2.5 mbar
Answer: 250 Pa = 0.0025 bar (2.5 mbar) — the gauge would barely register; use a manometer instead.
Question 4: A research paper reports fluid pressure of 750,000 Pa. Convert to bar for a process engineering team.
Solution:
Pressure in bar = 750,000 ÷ 100,000
= 7.5 bar
Answer: 750,000 Pa = 7.5 bar — within the range of standard industrial pneumatic systems.

Bridging Lab Data and Factory Floor
Research laboratories use precision instruments calibrated in pascals (or kPa), while factory equipment displays bar on mechanical Bourdon gauges. When scaling a process from lab to production, all pressure parameters must be translated. A lab reactor at 300,000 Pa becomes a "3 bar" setpoint on the plant DCS (Distributed Control System). This simple conversion prevents dangerous miscommunication between R&D teams (thinking in Pa) and operators (thinking in bar).
Pressure Sensors: Output in Pascals, Display in Bar
Modern industrial pressure transmitters (Endress+Hauser, WIKA, Rosemount) internally measure in pascals but can output any unit. A 4-20 mA transmitter with 0-10 bar range actually responds to 0-1,000,000 Pa. When calibrating, the reference standard is always traceable to SI (Pa), but the field display shows bar. Understanding that the sensor world lives in pascals while the plant world lives in bar simplifies troubleshooting discrepancies.
When Pascals Are Too Small for Industrial Use
A typical industrial pressure — say 7 bar for compressed air — is 700,000 Pa. Writing seven-digit numbers on P&ID diagrams and control narratives is impractical. This is precisely why bar exists: it provides human-friendly numbers (1-1000 range) for everyday industrial pressures. Reserve raw pascals for scientific calculations, FEA simulations, and instrument calibration where SI coherence matters more than readability.
Key Takeaways
- 1 Pa = 0.00001 bar — divide pascals by 100,000 to get bar.
- This is an exact conversion (no rounding): 1 bar ≡ 100,000 Pa.
- Lab instruments measure in Pa; factory gauges display bar.
- Standard atmosphere: 101,325 Pa = 1.01325 bar.
- For small pressures (Pa range), use millibar for practical gauge readings.
- Modern transmitters measure in Pa internally but display in user-configured units.
Pascal to Bar Conversion Formula
bar = pascal × 0.0000100
