- Scuba diving tanks
- Industrial pressure systems
- HVAC systems
- Hydraulic systems
📏 How This Converter Works
This is a bidirectional converter that works in real-time:
- PSI → Bar: When you type in the PSI field, the bar field automatically updates
- Bar → PSI: When you type in the bar field, the PSI field automatically updates
- No swapping needed: Both conversions happen simultaneously
- Real-time: Updates happen as you type, no button clicks required
// Conversion Constants:
1 bar = 100,000 Pascals
1 PSI = 6,894.76 Pascals
1 bar = 14.5038 PSI
1 PSI = 0.0689476 bar
// Example 1: Convert 30 PSI to bar
bar = 30 ÷ 14.5038 = 2.068 bar
// Example 2: Convert 2.5 bar to PSI
PSI = 2.5 × 14.5038 = 36.2595 PSI
1 bar = 100,000 Pascals
