What formula is being used to figure out the correct number of pixels/ems?

I've been trying to figure it out since the previous video, but how do you know that 80px is 4ems?

Is it something like: 400% divided by 100% equals 4, times 20px equals 80px...and the equivalent is the remainder from when you divide the % by 100? (So 4em?)

I feel like I'm making it way more complicated than it should be.
