12px to pt
At the default 16px root font size, 12px is commonly used for captions, labels and helper text.
12px =
9pt
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 12px equal to 9pt.
The formula is: pt = px × 0.75.
When to use pt
Points are a print unit where 1pt = 1/72 inch. They mainly matter for print stylesheets; on screen, CSS defines 1pt as 1.3333px at the reference 96dpi.
