How It Works
How to Convert PSI to Bar
Formulas
Bar = PSI × 0.0689476
kPa = PSI × 6.89476
1 PSI equals 0.0689476 bar and 6.89476 kilopascals. Standard atmospheric pressure is 14.696 PSI (1.01325 bar).
Worked Example
Convert 14.7 PSI (approximately 1 atmosphere) to bar and kPa.
value = 14.7
- 01Bar = 14.7 × 0.0689476 = 1.0135 bar
- 02kPa = 14.7 × 6.89476 = 101.353 kPa
