CSS CSS Basics (2014) Understanding Values and Units Em and Rem Units

To get to 53px, I converted 16px by dividing it to get the "em". But it doesn't work. Is this the right method?

body{ font-size: 16px; }

h2{ font-size: 3.313em; // convert to 53px }

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: 3.313em;
}

        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, divide the desired font size by the body font size. In this case:

  font-size: 3.3125em /* 53/16 = 3.3215 */

When sizing fonts, I usually do something like the code below ............. And then I can set all of type using REMs in increments of "1 REM=10px" This method can be helpful when using media queries and you want to reduce padding, margins etc... you can change the body font-size to 50% for example and it will scale everything on your site.

          html{
        font-size:62.5%
      }
