How to Convert Pascal to Kilopascal
- 1 Pa = 0.001 kPa
- 1 kPa = 1000 Pa
- Example: convert 15 Pa to kPa: 15 Pa = 15 × 0.001 kPa = 0.015 kPa
Formula
kPa = Pa ÷ 1000
Derivation from SI units:
- 1 Pa = 1 N/m² = 1 kg·m⁻¹·s⁻²
- 1 kPa = 10³ Pa
Both units are defined exactly, so the factor is exact. Pascal definition: pascal; Kilopascal definition: kilopascal.
Worked examples
- Standard atmospheric pressure, 101325 Pa, is 101.325 kPa.
101325 Pa × 0.001 = 101.325 kPa - A centrifugal fan developing 2500 Pa of static pressure delivers 2.5 kPa.
2500 Pa × 0.001 = 2.5 kPa

Where it's used
The kilopascal is the pascal scaled by 1000, so this conversion is a decimal shift of three places. Engineers switch to kPa once values pass a few thousand pascals, for example for fan pressures, pump heads and tyre pressures.

Frequently asked questions
How do I convert Pa to kPa in my head?
Divide by 1000, moving the decimal point three places to the left: 2500 Pa = 2.5 kPa.
How many kilopascals are in 1 pascal?
1 Pa = 0.001 kPa.
How do I convert pascals to kilopascals?
Multiply the value in Pa by 0.001, or divide it by 1000. For example, 15 Pa × 0.001 = 0.015 kPa.
Is the Pa to kPa conversion exact?
Yes. Both units are defined exactly, and 1 Pa is exactly 0.001 kPa.
