About this conversion
Intro
This page converts psi (psi) to bar (bar). Use it when a spec, sensor reading, datasheet, or calculation is in PSI and you need the equivalent value in Bar.
Definition
Pressure is force applied per unit area. It appears in fluids, gases, hydraulics, pneumatics, weather, and mechanical systems. Quick context on Bar: Bar (bar) are used in many technical fields (weather, industry, compressed gases). 1 bar = 100,000 Pa, close to standard atmospheric pressure.
Formula: PSI to Bar
bar = psi × 0.068947572932
This converter uses pascals (Pa) as a base unit. Multiply your psi value by the ratio to get bar. General form: bar = psi × (6894.757293168 Pa per psi) ÷ (100000 Pa per bar).
Worked examples
Example 1: 14.7 psi → 1.013529322096 bar
- Start with 14.7 psi.
- Multiply by the conversion ratio (0.068947572932).
- 14.7 × 0.068947572932 = 1.013529322096 bar.
Example 2: 30 psi → 2.06842718795 bar
- Start with 30 psi.
- Multiply by the conversion ratio (0.068947572932).
- 30 × 0.068947572932 = 2.06842718795 bar.
Example 3: 100 psi → 6.894757293168 bar
- Start with 100 psi.
- Multiply by the conversion ratio (0.068947572932).
- 100 × 0.068947572932 = 6.894757293168 bar.

FAQs
How do I convert PSI to Bar?
Use: bar = psi × 0.068947572932. Enter a value above and the converter calculates instantly.
How many Bar are in 1 PSI?
1 psi = 0.068947572932 bars.
What is Bar (bar) used for?
Bar (bar) are used in many technical fields (weather, industry, compressed gases). 1 bar = 100,000 Pa, close to standard atmospheric pressure.
Is Bar larger than PSI?
For PSI → Bar, the numeric result usually decreases because 1 psi is less than 1 bar.
Why do my values look very small or very large after converting?
Different pressure units have different scales (for example, Pa is small while MPa is large). That’s normal—only the unit scale changes, not the physical pressure.
Can I convert gauge pressure to absolute pressure here?
This page converts units only. Gauge vs absolute depends on reference pressure (typically atmospheric). Convert units first, then adjust using the appropriate reference.
What does “bar” mean in the result?
“bar” is the standard symbol for Bar. Your converted value is expressed in Bar (bar).
