kPa to atm – convert kilopascals to atmospheres
Convert kilopascals to atmospheres (kPa to atm) to see how many times atmospheric pressure a given reading represents, useful in science, medicine and engineering.
Open the interactive kPa → atm converter:
Use main converter (kPa → atm) or switch to atm → kPaEasily switch between Pa, kPa, bar, mbar, psi and atm in the main pressure converter.
Quick reference: kPa to atm
One atmosphere equals 101.325 kPa, so: atm = kPa ÷ 101.325. Examples:
| Pressure (kPa) | Pressure (atm, approx.) |
|---|---|
| 50 kPa | 0.49 atm |
| 101.3 kPa | 1.00 atm |
| 150 kPa | 1.48 atm |
| 200 kPa | 1.97 atm |
| 300 kPa | 2.96 atm |
| 500 kPa | 4.93 atm |
Why convert kPa to atm?
kPa to atm is useful when you:
- Interpret pressure readings as multiples of standard atmospheric pressure.
- Relate gas cylinder or vacuum levels to everyday “atm” references.
- Convert SI-based sensor outputs to atm for older tables or textbooks.
- Teach the relationship between kPa, bar and standard atmosphere.

A handy approximation is 10 kPa ≈ 0.1 atm, but for design work use the precise 101.325 kPa per atmosphere.
