How to type the Pi (π) symbol on a Mac or iPhone

It’s every math geek’s favorite day—March 14, there are still plenty of reasons why you would need to write about Pi. But while you can easily write the word “Pi” and everyone will know what you’re talking about, it’s way cooler to type the symbol π. It’s one of the most recognizable symbols in mathematics but it’s not found on any standard keyboard.

There’s an easy way to type it on your Mac:

  • Press and hold the option key (next to Command).
  • Type the letter “P”.
  • Release/repeat.

That’s it. No matter what app you’re in or the font you’re using, the Pi symbol will appear in the place of the letter “P.”

It’s a little trickier on the iPhone and iPad. First, you’ll need to add a new keyboard:

  • Head over to the Settings app.
  • Tap General and Keyboard.
  • Tap Keyboards, Add New Keyboard, and select Greek.

Then, when you want to type the Pi symbol, click the globe icon in the bottom left corner of the keyboard until you see the Greek keyboard. Tap the Pi symbol, which is the Greek letter “P” (top row, second from right). Then tap the Globe icon again to return to the English keyboard.

Here are a few other fun Pi facts to impress your friends:
