}Explanation
Formula: EM (16px context) = Points × 0.083333. Why: rem and em are relative units, so this route uses the page's explicit 16px baseline assumption before applying the target unit through CSS pixels.
Points (pt): a print-oriented unit equal to 1/72 of an inch, commonly used for typography and print specifications.
EM (16px context): a CSS relative unit based on the parent context font size. This converter assumes a fixed 16px context size.
This route is useful when translating between fixed CSS lengths and relative typography units so spacing, font sizing, and responsive UI rules stay on an explicit baseline.
This conversion is purely multiplicative because both units reduce through CSS pixels using a fixed 96 px per inch baseline and explicit relative-unit assumptions where needed.
