Be sure to carry all of the zeros that are significant  figures.
 
4650.00 g = 4650.00 x 10-3 kg = 4.65000 kg
 
You are correct.

Isn't this the same as 465,000. mg which also has 6 significant figures?

Comments

I meant to post this as a comment, not as an answer.  Sorry.
4.65000 kg = 4.65 x 106 mg = 4,650,000 mg
 
I guess that I'm asking "if there is a decimal at the end of the value 465,000. mg, isn't that still  6 sig. figs?  The same as 4.65000 kg.
Oops. Missed the decimal. It would be 4,759,000.  My bad. Was so hung up on dig figs forgot to look at magni.
