I am working on my Introduction to Chemistry exam review and I am stuck on a problem that asks to select the greatest pressure from given answer choices: 458 psi, 99.2 kPa, 1.41 atm, 0.822 bar. I know all of the conversions but my question is do I convert atm to mmHg and the rest to atm? What am I missing here? How can I find the greatest pressure?

Convert everything to the same unit, then compare.

Which unit - doesn't matter. Ordering will be the same.

Thank you!

Three of your values are within the same order of magnitude of each other whilst the other one way higher and should be obvious even without doing any calculations.
