How to Convert Bar to ksi
- 1 bar = 0.01450377377 ksi
- 1 ksi = 68.94757293 bar
- Example: convert 15 bar to ksi: 15 bar = 15 × 0.01450377377 ksi = 0.2175566066 ksi
Formula
ksi = bar × 0.01450377377302
or ksi = bar ÷ 68.94757293168
Derivation from SI units:
- 1 bar = 10⁵ Pa (exact, by definition)
- 1 ksi = 1000 psi = 1 kip/in² = 6.894757293168 MPa
- 1 bar = 100000 Pa ÷ 6894757.293168 Pa per ksi = 0.01450377377302 ksi
Both units are defined exactly, so the factor is exact. Bar definition: bar; ksi definition: ksi.
Worked examples
- A reading of 2 bar converts to 0.02900754755 ksi.
2 bar × 0.01450377377 = 0.02900754755 ksi - A value of 10 bar is 0.1450377377 ksi.
10 bar × 0.01450377377 = 0.1450377377 ksi

Where it's used
Bar are used for compressed air and pneumatics (6–8 bar), while ksi appear in yield and tensile strength in ASTM and ASME material specifications. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
