Hi,
See for yourself: gram.
What you seem to be missing is that there is a difference between the metric system and the practical systems based on the metric system. The cgs systems, the MKS system, the Rational MKSA system, and SI are all attempts to make something useful out of a bunch of poorly chosen units. They are all based on the original metric system. None of them use all three basic units as originally defined by that system.
I say nobody uses the metric system precisely because nobody does. At least, not outside of a laboratory. What's the outside temperature where you are in K? What is the peak torque of your car in Nt•m? What is its power output in watts? What's the distance to the nearest star in meters?
Any of those you need to calculate, even in your head, means you don't really use the metric system. You use some metric units when they are convenient, and then use whatever is convenient the rest of the time.
