- Since nuclear magnetic moments are smaller than electron magnetic moments, and the magnetic moment is a number representing the strength of a magnet, the electrons in a molecule determine the magnetic properties of a material, not the nuclei.

 Unfortunately, as in many fields these units are altered and renamed based on the application. This just causes confusion so the practice should be abolished, but until wiser heads prevail, here are some of the alternate units that magnetic moments are often expressed in:
