8px = 0.5rem

8 pixels converts to 0.5rem when the root font-size is 16px (the browser default). This conversion is calculated by dividing the pixel value by the base font size: 8 ÷ 16 = 0.5.

Formula

8px ÷ 16 = 0.5rem

CSS Example

/* 8px as rem */
.element {
  padding: 0.5rem; /* 8px */
}

When to Use 8px (0.5rem)

A value of 8px (0.5rem) is commonly used for small padding, gaps between icon elements, and compact spacing. In responsive web design, using 0.5rem instead of 8px ensures your compact UI elements scale proportionally when users change their browser font size settings.

Why Use REM?

REM units are relative to the root element's font-size, making them ideal for accessible, responsive designs. When you write 0.5rem instead of 8px, your layout respects user preferences — if someone sets their browser to a larger font size for readability, all your rem-based values scale up proportionally.
