Pressure / Pa → bar
Convert Pascals to Bars
Convert pressure differences or absolute pressures between consistent units. Convert Pascals (Pa) to Bars (bar). Find the formula, worked examples, unit definitions, and practical guidance below.
How to convert pascals to bars
This changes units only. Gauge and absolute pressures need a known ambient pressure to relate them; the converter does not add atmospheric pressure.
Use x for the value in Pa, b for the intermediate value in Pa, and y for the result in bar.
bar = Pa ÷ 100000
Worked examples
10 Pa ≈ 0.0001 bar
Step 1: (10 × 1) ≈ 10 Pa.
Step 2: 10 ÷ 100000 ≈ 0.0001 bar.20 Pa ≈ 0.0002 bar
Step 1: (20 × 1) ≈ 20 Pa.
Step 2: 20 ÷ 100000 ≈ 0.0002 bar.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Pascals
Pascals (Pa) measures pressure under the conventions above. The base value in Pa is (x × 1), where x is the numerical value in Pa. Factors shown here are rounded for display; calculations use the stored factor.
About Bars
Bars (bar) measures pressure under the conventions above. The base value in Pa is (x × 100000), where x is the numerical value in bar. Factors shown here are rounded for display; calculations use the stored factor.
