        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.

To convert pixels to ems the equation is TARGET / CONTEXT = RESULT. So you have to divide 53px by 16px to get the result in ems :)

The correct em value should be 53px/ 16px = 3.3125em I had a similar problem, I used pxtoem.com and the calculation came up as 3.313em. So I reverted to using a regular calculator and did the math 53 / 16 = 3.3125 and found this was correct.
