You don't. You compare the numbers you get across the engine. If
they are within 10% high to low, you go away happy.

Someone is almost certain to say "oh, 1 atmospher is 14.7 psi,
so just divide by 14.7 and you get CR". That's soundly wrong;
the air gets heated as it gets compressed, so it's not a simple
calculation at all.
