What Does F Mean in a Text?

F means "Fahrenheit" and "Female." It is also used to express sympathy. Here is more information about each of these definitions with examples.

Expression of Sympathy

The letter F is widely used online and in text messaging as an expression of sympathy. For example:
  • Charlie: My gran just died.
  • Jo: F. That sucks.
  • Sam: I flunked every subject!
  • Jo: F. Your parents are going to go crazy!
The use of F in this context stems from the FPS video game Call of Duty: Advanced Warfare, released in 2014. During a scene featuring the funeral of a major character, players were prompted to "Press F to Pay Respects." Although the scene was widely derided and sparked numerous viral memes, it also started the phenomenon of responding to bad news with the letter F.


The letter F is widely used, both online and offline, as an abbreviation of the word "female." In this context, it is particularly common on online dating sites and in personal ads (in the same was as M for "male"). For example:
  • f, 33, seeks m. Think of every girl you've ever dated. I'm nothing like them. (Unless you've ever dated a cuddly Italian chef called Rosa.)


Fahrenheit is a temperature scale first proposed by Daniel Gabriel Fahrenheit in 1724. Used primarily in the United States and its territories, F designates the freezing point of water as 32°F and the boiling point as 212°F at standard atmospheric pressure.

In contrast to Celsius ("C"), which is more globally adopted, the Fahrenheit scale is uniquely nuanced, with 180 divisions between freezing and boiling. To convert between the two, formulaic calculations are required.
  • Celsius to Fahrenheit Formula: (°C * 1.8) + 32 = °F
  • Fahrenheit to Celsius Formula: (°F - 32) / 1.8 = °C
Here is a converter that switches between the two:
