PX / REM Converter

Made for the task at hand.

Translate CSS sizing while keeping the project’s root font assumption visible. The browser default is often 16 pixels, but design systems can change it, so the reference size is always configurable.

How to use

1. Enter the numeric px or rem value without its suffix.
2. Set the root font size in pixels and choose the conversion direction.
3. Copy the converted value with the appropriate px or rem unit.
