Air Pressure Calculator
Convert between different pressure units (psi, bar, kPa, atm, etc.). Calculate pressure conversions for automotive, industrial, and scientific applications.
Step 1: Pressure Conversion
Common Pressure Conversions
1 psi = 0.0689476 bar
1 bar = 14.5038 psi
1 atm = 14.6959 psi
1 kPa = 0.145038 psi
Step 2: Pressure Applications
Typical Pressure Values
Car tires: 30-35 psi (2.1-2.4 bar)
Bicycle tires: 40-65 psi (2.8-4.5 bar)
Truck tires: 80-125 psi (5.5-8.6 bar)
Scuba tanks: 3000 psi (207 bar)
Atmospheric pressure: 14.7 psi (1.013 bar)

Example Calculation
Example: Convert 32 psi to bar and kPa
32 psi to bar:
32 × 0.0689476 = 2.206 bar
32 psi to kPa:
32 × 6.89476 = 220.63 kPa
32 psi to atm:
32 ÷ 14.6959 = 2.177 atm
