What is the Unicode code point for one third?

The one third symbol is U+2153, officially named VULGAR FRACTION ONE THIRD. It is part of the Number Forms Unicode block.

What is the HTML entity for ⅓?

There is no named HTML entity for one third. Use the numeric entity ⅓ or the hex form ⅓.

How do I type ⅓ on Windows?

In Microsoft Word, type 2153 then press Alt+X to convert it to ⅓. Outside Word, this code point has no standard numpad Alt code because it falls outside the legacy Windows-1252 character set, so copy-paste is the most reliable option.

How do I type ⅓ on a Mac?

Enable the Unicode Hex Input source in Keyboard settings, switch to it, then hold Option and type 2153.

Is ⅓ the same as writing "1/3"?

They look similar but are different characters. "1/3" is three separate characters (digit, slash, digit), while ⅓ is a single precomposed Unicode character that some fonts render with a true fraction glyph.

Will ⅓ display correctly everywhere?

Most modern fonts and browsers support this character since it has been in Unicode since version 1.1. Very old or limited fonts may fall back to a generic box or missing-glyph marker.
