Convert Kilopascals to Atmospheres
1 kilopascal is 0.009869 atm. One kilopascal is exactly 0.00986923266716 atmospheres.
One kilopascal is 0.0098692327 atmospheres. To convert kilopascals to atmospheres, multiply by 0.0098692327; to go the other way, divide by 0.0098692327 or multiply by 101.325. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A thousand pascals, and the unit metric tyre placards and weather stations use.

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 kilopascals to atmospheres?
- 1.Take the measurement in kilopascals.
- 2.Multiply by 0.0098692327 — that is how many atmospheres fit in one kilopascal.
- 3.To go back the other way, divide by 0.0098692327, or multiply by 101.325.
Worked example: 25 kilopascals to atmospheres
- Formula
- kPa × 0.0098692327 = atm
- Arithmetic
- 25 × 0.0098692327 = 0.246731 atm
- Answer
- 25 kPa = 0.246731 atm
The factor is rounded for display; the figure above is computed from the full value.

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.
What is a standard atmosphere?
Exactly 101,325 pascals by definition, not by measurement — it was fixed as a reference, and the real pressure outside your window is never precisely it.
How many atmospheres are in a kilopascal?
One kilopascal is 0.0098692327 atmospheres. Going the other way, one standard atmosphere is 101.325 kilopascals. 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.
