Phi (uppercase Φ / lowercase φ / φ) is the 21st letter of the Greek alphabet. The uppercase symbol has various uses, such as the cumulative distribution function of standard normal deviation in statistics. The lowercase symbol has two variants, φ and φ. It is used more often, such as representing the golden ratio in mathematics, or within cartography, geodesy, navigation, and latitude.

Here’s some examples of how the Phi upper case and Phi lower case symbols look in common Office fonts in Word 365. Fonts such as Calibri supports the alternative variant for the lowercase Phi symbol as “φ” whilst the remaining are of it’s variant “φ”.
