Why no units for K?

In class I noticed we don't have any units for K. Are there none? why?

K has no units. In class it was mentioned that concentration estimates chemical activities (a topic more advanced than this course requires), which has no units, and so K also has no units.

K has no units because when elaborated, the units cancel out. The k equation we use is technically an abbreviation.

Equilibrium constants are calculated using activity, and activity is unitless, so K is also unitless.
