How to Convert Millibar to ksi
- 1 mbar = 0.00001450377377 ksi
- 1 ksi = 68947.57293 mbar
- Example: convert 15 mbar to ksi: 15 mbar = 15 × 0.00001450377377 ksi = 0.0002175566066 ksi
Formula
ksi = mbar × 0.00001450377377302
or ksi = mbar ÷ 68947.57293168
Derivation from SI units:
- 1 mbar = 10⁻³ bar = 100 Pa = 1 hPa
- 1 ksi = 1000 psi = 1 kip/in² = 6.894757293168 MPa
- 1 mbar = 100 Pa ÷ 6894757.293168 Pa per ksi = 0.00001450377377302 ksi
Both units are defined exactly, so the factor is exact. Millibar definition: millibar; ksi definition: ksi.
Worked examples
- A reading of 20 mbar converts to 0.0002900754755 ksi.
20 mbar × 0.00001450377377 = 0.0002900754755 ksi - A value of 900 mbar is 0.0130533964 ksi.
900 mbar × 0.00001450377377 = 0.0130533964 ksi

Where it's used
Millibars are used for weather maps and barometers (sea level ≈ 1013 mbar), 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.
