One atmosphere is equal to 101.325 kilopascals.

Explanation:
Understanding atmospheric pressure in different units helps you convert quickly between common pressure standards. One atmosphere is defined as 101.325 kilopascals, so expressing that same pressure in kilopascals gives exactly 101.325 kPa. That’s the precise, widely used standard for 1 atm. The other options mix up the units or magnitudes. 101.325 pascals is far too low—it would be about 0.001 atm. 760 kilopascals is much higher than 1 atm (around 7.5 atm). And 1,013.25 kilopascals is about 10 atm. So the correct expression is 101.325 kilopascals.
