Cuz the gram came before the SI system and the kilogram is a much more useable unit. The original m-g-s are based on physical things, like m being a subdivision of the length from the North Pole to the Equator going through Paris, and s being related to the time of a pendulum with certain length swinging or smth

A gram is the weight of 1 mL of water, roughly.

I remember in some old astronomy textbooks they used units based on CGS (cm-g-s) as opposed to MKS (m-kg-s). It was pretty weird, as they had terms to go with that system like dynes instead of newtons for force. But at least it wasn't imperial.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
