How to Convert Kilopascal to ksi
- 1 kPa = 0.0001450377377 ksi
- 1 ksi = 6894.757293 kPa
- Example: convert 15 kPa to ksi: 15 kPa = 15 × 0.0001450377377 ksi = 0.002175566066 ksi
Formula
ksi = kPa × 0.0001450377377302
or ksi = kPa ÷ 6894.757293168
Derivation from SI units:
- 1 kPa = 10³ Pa
- 1 ksi = 1000 psi = 1 kip/in² = 6.894757293168 MPa
- 1 kPa = 1000 Pa ÷ 6894757.293168 Pa per ksi = 0.0001450377377302 ksi
Both units are defined exactly, so the factor is exact. Kilopascal definition: kilopascal; ksi definition: ksi.
Worked examples
- A reading of 20 kPa converts to 0.002900754755 ksi.
20 kPa × 0.0001450377377 = 0.002900754755 ksi - A value of 300 kPa is 0.04351132132 ksi.
300 kPa × 0.0001450377377 = 0.04351132132 ksi

Where it's used
Kilopascals are used for tyre pressure outside the United States (about 200–250 kPa for cars), 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.

Frequently asked questions
How many ksi are in 1 kilopascal?
1 kPa = 0.0001450377377 ksi.
How do I convert kilopascals to ksi?
Multiply the value in kPa by 0.0001450377377, or divide it by 6894.757293. For example, 15 kPa × 0.0001450377377 = 0.002175566066 ksi.
Is the kPa to ksi conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
