I need help on a px to em conversion question.

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.

I have done this by using 16px as the base and then converting to em and getting 3.3.13em. Where do you think I am going wrong? Please advise.

header {
  font-size: 1.8rem;

.title {
  font-size: 1.625rem;
}

h1 {
  font-size: 5.625rem;
}

h2 {
    font-size: 3.313em;
}

I was able to figure it out! PXtoEM.com’s calculation was incorrect so I used the PX to EM converter by W3Schools and was able to get the right conversion. Thanks for the reply!

Also you can just divide 53 by 16 and get the correct answer of 3.3125em instead of using a converter.

Hi Shaoib,

The challenge checker can be fussy about rounding. Try replacing your value that is rounded to 3DP with the exact value.

Cheers
