I agree with metric on general principles but I believe they could have made it a bit neater. For instance if the basic unit of length had been chosen so that what is now a a decimeter would have been called the meter, then the basic unit of mass could have been a cube one (deci)meter on a side then what we now call a kilogram would have been the gram.
That way the basic units, sans prefixes, would have been a bit more more "human-scaled". I realize it's all a bit arbitrary in the end, but I find it less than ideal that the units that are used most often in ordinary usage all seem to require prefixes. A human weight is best measured in KILOgrams, a human height in CENTImeters, etc. Does any of that make sense or have I been up too late again? Rod
