About This Tool

The Pixel to Rem/EM Converter is an essential utility for modern web developers working on responsive and scalable designs. It helps you easily convert between fixed pixel (px) values and relative units like `rem` (relative to the root element's font-size) and `em` (relative to the parent element's font-size). You can set a custom base font size for your project and instantly get the correct relative values, streamlining your CSS workflow and improving accessibility.

How to Use
  1. First, set the "Base Font Size" in pixels. This is typically 16px for most browsers, but you should change it to match your project's root `font-size`.
  2. Enter a value in any of the three input cards: "Pixels (px)", "REM", or "EM".
  3. The other two fields will automatically update in real-time to show the converted values based on your input and the base font size.
  4. Click the copy icon next to any value to copy it to your clipboard.
