Kilopascals to Atmospheres (kPa to atm) Converter
1 kilopascal equals 0.00986923 atmospheres — multiply kilopascals by 0.00986923 to convert. The standard atmosphere is defined as exactly 101.325 kPa, so each kilopascal is 1 ÷ 101.325 of an atmosphere.
The formula
Multiply the kilopascal value by 0.00986923 to get atmospheres:
atm = kPa × 0.00986923
For example, 101.325 kPa × 0.00986923 = 1 atm. To reverse, divide atm by 0.00986923 (or multiply by 101.325).

Where this conversion is used
Atmospheres are a natural reference for pressure in chemistry, scuba diving, and meteorology, where conditions are compared to sea-level air pressure. Kilopascals are the SI-based unit on weather instruments and engineering specs. Converting between them helps chemists apply the ideal gas law, divers gauge depth pressure, and students interpret barometric readings.
FAQ
How many atmospheres are in a kilopascal?
One kilopascal equals 0.00986923 atm. Multiply the kPa figure by 0.00986923 — for example, 100 kPa = 0.986923 atm.
What is the formula to convert kPa to atm?
Use atm = kPa × 0.00986923. The tool applies this exact factor automatically so you never round by hand.
How do I convert atmospheres back to kilopascals?
Divide by 0.00986923, or multiply by 101.325. For instance, 1 atm = 101.325 kPa.
Is the conversion exact?
The standard atmosphere is exactly 101.325 kPa, so the factor is exact; 0.00986923 is that reciprocal rounded to eight places.
