How to Convert EM to PX
Converting EM to PX is simple. First, determine the parent element's font size, then multiply it by the EM value to get the equivalent pixel (px) size.
EM to Pixels Conversion Formula
To manually convert EM to pixels, use the following formula:
Pixels = EM × Font Size
This method ensures accurate font scaling in CSS, making it essential for responsive web design and typography adjustments.
How EM Works
In CSS, the em
unit is relative to the font size of its parent element. For example:
<section>
<p>How EM works.</p>
</section>
When you set a font size for the <section>
element, it determines the base size for its children:
section {
font-size: 16px;
}
Now, if you assign 2em
to the <p>
element:
p {
font-size: 2em;
}
The font size of the paragraph will be twice the size of its parent <section>
, which means 32px (2 × 16px).
