Convert Bar to Pascal
Convert Bar to Pascal exactly by multiplying by 100,000—ideal for industrial, diving, and lab calculations.
How to Convert Bar to Pascal
To convert Bar to Pascal, multiply bar by 100,000 because 1 bar = 100,000 Pa.
Conversion Formula:
value * 100000Understanding the Conversion
Bar to Pascal moves from a convenient industrial unit to the SI base unit. Multiply bar by 100,000 to reach Pascals. Use this when scientific equations, simulations, or compliance documents require Pa while equipment or vendors specify bar. Because the factor is exact, you do not lose precision.
Reference: 1 bar = 100,000 Pa ≈ 1,000 mbar ≈ 14.5038 psi ≈ 750.062 Torr. Standard atmosphere (≈1.01325 bar) equals 101,325 Pa. The conversion is reversible—divide Pascals by 100,000 to return to bar.
Conversion Examples
Example: Convert 2.5 bar to Pa
- Step 1: 2.5 × 100,000 = 250,000.
- Step 2: Result is 250,000 Pa.
- Step 3: Straightforward scaling.
2.5 bar = 250,000 Pa
Typical compressor range.
Example: Convert 1.01325 bar to Pa
- Step 1: 1.01325 × 100,000 = 101,325.
- Step 2: Result is 101,325 Pa.
- Step 3: Atmospheric reference.
1.01325 bar = 101,325 Pa
Sea-level atmosphere.
Example: Convert 0.5 bar to Pa
- Step 1: 0.5 × 100,000 = 50,000.
- Step 2: Result is 50,000 Pa.
- Step 3: Lower-pressure scenario.
0.5 bar = 50,000 Pa

Conversion Formula
Bar is defined as 10^5 Pascals. Multiplying by 100,000 moves to the SI base unit.

Unit Definitions
Bar (bar)
Metric-adjacent unit, 100 kPa.
1 bar = 100,000 Pa = 100 kPa ≈ 14.5038 psi ≈ 750.062 Torr ≈ 1,000 mbar.
Pascal (Pa)
SI base unit of pressure.
Pa to bar divide by 100,000; Pa to kPa divide by 1,000; Pa to psi divide by 6,894.76.
Common Use Cases
- Industrial specs: convert bar to Pa for SI-based models.
- Diving: translate bar readings to Pascals for calculations.
- Process control: feed SI-only systems with Pa values.
- Compliance: report pressures in Pascals per standards.
- Education: demonstrate bar-to-Pa scaling.
Frequently Asked Questions
Is bar an SI unit?
No, but it is widely used. Pascals are the SI base unit.
How close is bar to atm?
1 bar ≈ 0.9869 atm; 1 atm ≈ 1.01325 bar.
Do I lose accuracy?
No. The factor is exact.
