REM to PX Converter
Convert a rem value to pixels — useful for design handoff or debugging computed sizes.
Browsers default to a 16px root font size unless overridden by the page's CSS or the user's browser settings — adjust it above if your project uses a different base.
Processing happens locally in your browser. Nothing you enter is uploaded.
How It Works
Enter a rem value and the root font size. The pixel equivalent updates instantly.
px = rem × root font size (16px by default)
Example
1.5rem is 24px at the default 16px root font size.
