1 rem = root font size
CSS converts every length through pixels. The absolute units are fixed to each other: 1 in = 2.54 cm = 96 px = 72 pt = 6 pc, and 1 Q is a quarter of a millimetre. The font-relative units depend on the page: 1 rem is the root element's font size, and when you set font-size, 1 em (or 100%) is the parent's font size. The converter turns the value into pixels, then divides by the pixels in one target unit.
Front-end developers use it to turn a design's pixel sizes into rem, so text follows the reader's browser font setting: with the default 16 px root, 24 px is 1.5 rem. Print designers use the pixels-per-inch field instead; at 300 DPI a 10 mm logo needs about 118 pixels.
On screens a CSS inch is not a measured inch. Browsers anchor 96 px to a reference pixel of about 0.0213° of visual angle, so physical units match a ruler only in print.

16 pixels by default. One rem equals the font size of the root html element, and the major browsers set that to 16 px unless the reader changes the default font size or the stylesheet sets html { font-size }. Setting html { font-size: 62.5% } makes 1 rem = 10 px. The W3C CSS Values and Units specification defines rem; the 16 px figure is the browser default, not part of the specification.
Multiply pixels by 0.75; to go from points to pixels, multiply by 4/3 (about 1.333). Both factors follow from the W3C CSS rule 1 in = 96 px = 72 pt, so 1 px = 72/96 pt. Body text at 16 px is 12 pt, and 11 pt text from a word processor is about 14.67 px.
rem always refers to the root element's font size; em refers to the current element's font size, or to the parent's when used on font-size itself. So em compounds when nested: a list set to 1.2em inside another list set to 1.2em has text 1.44 times the outer size, while 1.2rem stays at 19.2 px with a 16 px root however deep it sits.
Use rem if text should follow the reader's browser font-size setting. Page zoom enlarges px and rem alike, but the default font-size preference changes only rem, em and percentage sizes. WCAG 2.1 success criterion 1.4.4 (level AA) requires text that can be resized to 200% without loss of content or function; browser zoom can meet it with px, and rem also honours the font-size preference.
Only in print. CSS defines 1 in as exactly 96 px, and on screens browsers anchor the pixel to the W3C reference pixel: one pixel of a 96 DPI screen seen from 28 in away, a visual angle of about 0.0213°. Phones are held closer and use smaller pixels, so a 96 px box measures well under an inch on most phones. Printers anchor to physical units, so 1 in prints as 25.4 mm.
