About these units
Browsers turn every CSS length into pixels. rem is relative to the root font size and em to the parent element's font size; both are 16px in every major browser unless the page or the user changes it. 1pt is 1/72 inch and 1px is 1/96 inch, so 1pt = 1.333px. vw is 1% of the viewport width, so its pixel size depends on the screen.
FAQ
› How do I convert em to px?
1 em = 16 px. To convert, multiply the value by 16: 2 em = 32 px.
› What is 1 px in em?
1 px = 0.0625 em. The reverse formula is em = px ÷ 16.
› Why use rem instead of px?
rem sizes follow the user's browser font size setting, which helps accessibility, and changing one root value resizes the whole layout consistently.
› What is the difference between rem and em?
rem always uses the root (html) font size. em uses the font size of the element's parent, so nested em values compound.
