Type Zeta – lower case ζ  into Microsoft Word, Excel, PowerPoint or Outlook.  Both in Office for Windows and Office for Mac. 

Zeta – lower case ζ  symbol is the 6th letter of the Greek alphabet. It is used for various mathematically and scientific reasons, such as representing the Riemann zeta function, the heat flux through a plane or relative vorticity in the ocean or atmosphere.  

The uppercase Zeta is not normally used, because it’s identical to the Latin Z letter.
