28rem to px

28rem = 448px

At the browser default root font size of 16 px. Change it and this number changes — see below.

How it is calculated

One rem is 16px, so:

28rem × 16 = 448px

Reversing it, 448px × 0.0625 returns 28rem.

28rem at other root font sizes

rem is measured against the root element, so the answer above holds only while that is 16 px. A visitor who has raised their browser's default — the accessibility setting rem exists to respect — is reading your page at one of the larger rows.
