Units is an informational calculator, in English, at units.dozotools.com. It is provided as-is. A result can differ from the computed style in a browser.

Check the computed value in your own page before you ship CSS. Root font size, parent font size, user zoom, and the real viewport all change what a length means in a layout. The CSS inch is 96px. A physical screen does not have to agree. ch, ex, and lh depend on the font you measured, not on the default guesses.

Do not rely on this site for a legal, financial, or accessibility audit. You are responsible for the CSS you publish.
