℉ folds the degree sign and a capital F into one Unicode character — quick to paste, though most style guides still prefer the two-character °F. Click any symbol to copy it instantly.
The degree Fahrenheit sign (℉, Unicode U+2109) is a precomposed character in the Letterlike Symbols block combining the degree sign (°) with a capital F. Like its Celsius counterpart ℃, it was added to Unicode largely for lossless round-tripping of legacy East Asian text, where a temperature reading often filled a single character cell. In everyday writing the recommended form is the degree sign followed by a plain F (°F), but the single ℉ is the fastest glyph to copy when that is all you need.
The single-character ℉ and the two-character °F sequence Unicode prefers.
Marks that get substituted for ℉ — each is a distinct character.
The Fahrenheit scale is named after Daniel Gabriel Fahrenheit (1686–1736), the German-Dutch physicist who introduced it in 1724 and had built the first reliable mercury-in-glass thermometer a decade earlier. On his scale water freezes at 32° and boils at 212° — a 180-degree span — and it remains the everyday temperature scale in the United States and a few territories. The two scales meet at exactly −40°, where −40 ℃ equals −40 ℉.
Unicode places ℉ at U+2109 in the Letterlike Symbols block and marks it as a compatibility character with the decomposition ° (U+00B0) and F (U+0046). It was encoded so that temperature values from older Japanese, Korean, and Chinese character sets — which often stored the reading in one fixed-width cell — could survive conversion to Unicode and back. As with ℃, the standard and the W3C recommend writing °F in normal prose and keeping the single ℉ for compatibility contexts.
| Platform / Tool | Method |
|---|---|
| Windows (Word / Unicode input) | Type 2109, then press Alt+X |
| Mac | Character Viewer (Cmd+Ctrl+Space), search "degree fahrenheit" |
| HTML | ℉ or ℉ |
CSS content | content: "\2109" |
| Recommended form | Degree sign ° followed by F |
For normal writing, use °F — the degree sign followed by a capital F. The single ℉ (U+2109) exists mainly for round-tripping legacy East Asian text and fixed-width layouts, so it is fine to paste but is not the typographic default.
In Word or any app that supports it, type 2109 and press Alt+X, or paste ℉ from this page. There is no dedicated Fahrenheit key.
Yes. ℃ (U+2103) and ℉ (U+2109) are each one precomposed character that Unicode treats as compatibility-equivalent to the two-character sequences °C and °F.
−40°. The Celsius and Fahrenheit scales cross at exactly minus forty, so −40 ℃ and −40 ℉ are the same temperature.
