Thin Space
The thin space is a narrow blank, typically about one-fifth or one-sixth of an em. Style guides use it to group digits in large numbers, as in 1 000 000 under SI convention, to separate a number from its unit, and to keep nested quotation marks apart. In math typesetting it adds a little breathing room around symbols.

Good to know
Don’t mix it up: It is often confused with the narrow no-break space (U+202F), which has a similar width but prevents a line break.
Tip: Because a thin space allows a line break, use U+202F when a number and its unit must stay on the same line.
Display: the character itself is always the same code point, but its shape comes from the font on the device showing it. If you see an empty box, the font lacks this glyph—the text is still correct.
