Challenge re font-size

h2 parent element has a font-size of 16px. I’m asked to give the h2 a font-size value equivalent to 53 px. Therefore I have calculated out 53 / 16 = 3,312 and provided a value of 3.312em but received an error. Why?

style.css 
/* Complete the challenge by writing CSS below */

header {
  font-size: 1.8em;
}

.title {
  font-size: 1.625rem;
}

h1 {
  font-size: 5.625rem;
}

h2 {
    font-size: 3.312em;
}

        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 challenge wants you to use full precision and 53 / 16 = 3.312‍5.
