Understanding This Calculator
Pressure Unit Conversions

Pressure is the expected force applied perpendicular to the surface of an object per unit area.
1. Bar to PSI
1 Bar is approximately equal to 14.5038 PSI (Pounds per Square Inch).
PSI = Bar × 14.5038
Example 1: Convert 2 Bar to PSI
- Formula: 2 × 14.5038
- Result: 29.01 PSI
Example 2: Convert 10 Bar to PSI
- Formula: 10 × 14.5038
- Result: 145.04 PSI
2. Atmosphere to Pascal
1 Standard Atmosphere (atm) is equal to 101,325 Pascals (Pa).
Pa = atm × 101,325
Example 1: Convert 1 atm to Pa
- Formula: 1 × 101,325
- Result: 101,325 Pa
Example 2: Convert 0.5 atm to Pa
- Formula: 0.5 × 101,325
- Result: 50,662.5 Pa
