About REM to PX Conversion

What is REM?

REM (Root Em) is a relative CSS unit that is based on the font size of the root element (typically 16px by default). It's useful for creating scalable, responsive designs that adapt to user preferences.

What is PX?

PX (Pixels) is an absolute unit that represents a fixed size on the screen. It doesn't scale with user preferences or parent elements, making it useful for precise measurements.

The Conversion Formula

1 REM = Base Font Size (default 16px)

If you change your base font size to 20px, then 1 REM = 20px.
