Excuse me, could you please elaborate on the comparison you're making here? I'm a bit confused about the connection between the letter "G" and a centrifuge. Are you referring to a specific aspect of centrifuge technology, or is there some sort of terminology in the field that uses "G" as an abbreviation or shorthand? Could you clarify the context and what you mean by saying "What is the same as G in centrifuge?" so that I can provide a more accurate answer?
