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

CSS Basics > Stage 3 - Understanding Values and Units > Challenge Task

Question: Finally, create a new rule that targets the h3. Using the same parent font-size context, give the h3 a font-size value in ems equivalent to 20px.

My answer:

'''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: 3.3125em; }

h3 { font-size: 1.250em; } '''

Result: Bummer! Is the font-size of 'h3' an em value equivalent to 20px?

P.S.

Anyone can tell me what's the problem with this code? Why the generated value converted at a website like [ http://pxtoem.com/ ] isn't enough to be accepted as correct?

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: 3.3125em;
}

h3 {
  font-size: 1.250em;
}

        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.
