How to Convert Kilopascal to psi
- 1 kPa = 0.1450377377 psi
- 1 psi = 6.894757293 kPa
- Example: convert 15 kPa to psi: 15 kPa = 15 × 0.1450377377 psi = 2.175566066 psi
Formula
psi = kPa × 0.1450377377302
or psi = kPa ÷ 6.894757293168
Derivation from SI units:
- 1 kPa = 10³ Pa
- 1 psi = 1 lbf/in² = (0.45359237 kg × 9.80665 m/s²) ÷ (0.0254 m)² = 6894.757293168 Pa
- 1 kPa = 1000 Pa ÷ 6894.757293168 Pa per psi = 0.1450377377302 psi
Both units are defined exactly, so the factor is exact. Kilopascal definition: kilopascal; psi definition: psi.
Worked examples
- A car tyre at 220 kPa is at 31.9083023 psi.
220 kPa × 0.1450377377 = 31.9083023 psi - Standard atmospheric pressure, 101.325 kPa, is 14.69594878 psi.
101.325 kPa × 0.1450377377 = 14.69594878 psi

Frequently asked questions
What is a quick way to convert kPa to psi?
Multiply by 0.145 (or divide by 6.895): 200 kPa ≈ 29.01 psi.
How many psi are in 1 kilopascal?
1 kPa = 0.1450377377 psi.
How do I convert kilopascals to psi?
Multiply the value in kPa by 0.1450377377, or divide it by 6.894757293. For example, 15 kPa × 0.1450377377 = 2.175566066 psi.
Is the kPa to psi 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).
