why is 3.313em not correct?

The task was: Create a new rule that targets the h2. The h2's parent element has a font-size value of 16px. Use an em unit to give the h2 a font-size value equivalent to 53px.

        As spawning season approaches, the fish acquire a humpback and protuberant jaw. After spawning, they die and their carcasses provide a feast for gatherings of mink, bears, and Bald eagles.

The answers you'll get from the online pixel to em conversion tools won't work with this Task because they round up the number. To pass Task 2 you need an exact answer and that requires you to do it either in your head or on a calculator. To find the exact answer the system is looking for you divide 53px (value equivalent to) by 16px (parent element value). That gives you 3.3125em.
