How many kilopascals are in one atmosphere?

One standard atmosphere is exactly 101.325 kilopascal.

Detailed answer

The standard atmosphere is defined as 101,325 Pa. Since 1 kPa = 1,000 Pa, 101,325 Pa = 101.325 kPa exactly.

Relationship context

Chemistry and physics problems often cite 1 atm; weather and building science may use kPa or hPa.
