How to Convert Kilopascal to Pascal
- 1 kPa = 1000 Pa
- 1 Pa = 0.001 kPa
- Example: convert 15 kPa to Pa: 15 kPa = 15 × 1000 Pa = 15000 Pa
Formula
Pa = kPa × 1000
Derivation from SI units:
- 1 kPa = 10³ Pa
- 1 Pa = 1 N/m² = 1 kg·m⁻¹·s⁻²
Both units are defined exactly, so the factor is exact. Kilopascal definition: kilopascal; Pascal definition: pascal.
Worked examples
- A HEPA filter with an initial resistance of about 0.25 kPa is at 250 Pa.
0.25 kPa × 1000 = 250 Pa - A fan rated for 3 kPa of static pressure can deliver up to 3000 Pa.
3 kPa × 1000 = 3000 Pa

Frequently asked questions
Do filter datasheets use kPa or Pa?
Usually pascals, e.g. an initial pressure drop of 100 Pa and a recommended final pressure drop of 250–450 Pa. Divide by 1000 for kPa.
How many pascals are in 1 kilopascal?
1 kPa = 1000 Pa.
How do I convert kilopascals to pascals?
Multiply the value in kPa by 1000. For example, 15 kPa × 1000 = 15000 Pa.
Is the kPa to Pa conversion exact?
Yes. Both units are defined exactly, and 1 kPa is exactly 1000 Pa.
