What is the pressure value for standard states?

The textbook uses 1 bar for standard states but if I remember correctly we used 1 atm in class. Which one should we use on the exam?

1 bar is approx. 1 atm!
They are interchangeable.

1 atm = 1.01325 bar
1 bar = 100,000 Pa

For most questions that don't require extremely accurate measurements, though, there's not enough difference to necessitate this distinction.
