since he initially used 53px/16px to calculate 3.3125em. why not the same for the bottom margin?

1 em is equal to the font size of the element to which is applied. If em units are declared on child elements in which a font-size property isn't defined, they'll inherit their font-size value from their parent. This is why in this example the margin-bottom property em unit is relative to h3 font size, while the h3 font-size property em unit is relative to the body font size
