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. 1.Take the measurement in pascals.
  2. 2.Multiply by 0.001 — that is how many kilopascals fit in one pascal.
  3. 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.

Questions people actually ask

How many kilopascals are in a pascal?
0.001. A thousand pascals, and the unit metric tyre placards and weather stations use. Atmospheric pressure at sea level is about 101 kPa.
How do I convert kilopascals back to pascals?
Divide by 0.001, or multiply by 1000 — they are the same operation.

Kilopascals to pascals — the same conversion the other way.
