### Units of Hz in Equations

When using Einstein's equation, given MHz, do you have to convert this to Hz for the formula to work? I just want to make sure, but I would assume so since Hz is the base unit and M is just a prefix.

MHz means "mega hertz" and is equal to 1,000,000 Hz, so you're right in saying that M is just a prefix. When you do a problem always convert back into the base unit unless the problem specifically tells you otherwise.
