1.5rem to px

How the conversion works

CSS unit conversions assume a default root font size of 16px (the browser default), where 1rem = 16px and 1em = 16px in a default context. Points use the CSS reference of 96dpi, so 1pt = 1.3333px. That makes 1.5rem equal to 24px.

The formula is: px = rem × 16.

When to use px

Pixels are absolute and predictable, which is why designers and design tools usually think in px. Converting to px is handy when translating a mockup’s exact measurements into relative units like rem.
