How to Convert ksi to Bar
- 1 ksi = 68.94757293 bar
- 1 bar = 0.01450377377 ksi
- Example: convert 15 ksi to bar: 15 ksi = 15 × 68.94757293 bar = 1034.213594 bar
Formula
bar = ksi × 68.94757293168
Derivation from SI units:
- 1 ksi = 1000 psi = 1 kip/in² = 6.894757293168 MPa
- 1 bar = 10⁵ Pa (exact, by definition)
- 1 ksi = 6894757.293168 Pa ÷ 100000 Pa per bar = 68.94757293168 bar
Both units are defined exactly, so the factor is exact. ksi definition: ksi; Bar definition: bar.
Worked examples
- A reading of 20 ksi converts to 1378.951459 bar.
20 ksi × 68.94757293 = 1378.951459 bar - A value of 65 ksi is 4481.592241 bar.
65 ksi × 68.94757293 = 4481.592241 bar
