Convert Pascals to Kilopascals
1 pascal is 0.001 kPa. One pascal is exactly 0.001 kilopascals.
One pascal is 0.001 kilopascals. To convert pascals to kilopascals, multiply by 0.001; to go the other way, divide by 0.001 or multiply by 1000. The factor is exact rather than rounded: it follows from NIST Special Publication 811. The SI unit: one newton spread over one square metre.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert pascals to kilopascals?
- 1.Take the measurement in pascals.
- 2.Multiply by 0.001 — that is how many kilopascals fit in one pascal.
- 3.To go back the other way, divide by 0.001, or multiply by 1000.
Worked example: 25 pascals to kilopascals
- Formula
- Pa × 0.001 = kPa
- Arithmetic
- 25 × 0.001 = 0.025 kPa
- Answer
- 25 Pa = 0.025 kPa
The factor is exact, so this figure is exact too — only the display is rounded.

What is a pascal?
The SI unit: one newton spread over one square metre. It is a small pressure — a sheet of paper resting on a table is about one pascal — which is why the kilopascal is what instruments actually read.
What is a kilopascal?
A thousand pascals, and the unit metric tyre placards and weather stations use. Atmospheric pressure at sea level is about 101 kPa.
How many kilopascals are in a pascal?
One pascal is 0.001 kilopascals, exactly. Going the other way, one kilopascal is 1000 pascals. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
