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
  1. 01Bar = 14.7 × 0.0689476 = 1.0135 bar
  2. 02kPa = 14.7 × 6.89476 = 101.353 kPa
