What is the conversion of 125 mmHg into atm?

Answer 1

The relationship between atmospheres and mmHg is #"1atm" = "760mmHg"#

Using that equality, you can calculate two conversion factors, or ratios, that add up to one:

#"1atm"/"760mmHg"# = #"760mmHg"/"1atm"# = #"1"/"1"#

To ensure that mmHg cancels out and leaves atm in the answer, use dimensional analysis to multiply 125mmHg times the conversion factor with the atm unit on top and mmHg on the bottom.

#"125mmHg"# x #"1atm"/"760mmHg"# = #"0.164atm"# The mmHg would cancel, leaving you with atmospheres in your answer.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
