From wikipedia:

If you are comparing the strength of forces, and you are using these numbers to do so, I would have thought that these numbers would represent units of - well,The coupling constant arises naturally in a quantum field theory. A special role is played in relativistic quantum theories by coupling constants which are dimensionless, i.e., are pure numbers.

*force.*

Clearly I must be missing something.

Thanks.
