It does not bother me, it turns out that having an inconsistent measuring system is not actually that bad. and metric, it turns out has no more purity in it's base units than any other system.
Take the meter, the group setting up the metric system was searching hard for something that was close in size to a yard so they choose 1/10_000_000 the distance from the pole to the equator. nothing wrong with that, but it is not really better than any other arbitrary unit, and with the better defined ways to calculate it(now defined as 1/299792458 of a light second), just as random.
Or celsius, base it on 100 units between the freezing and boiling points of water, not a terrible thing to use, however with the later discovery of absolute zero, they needed a scale that used that, but did not try to redefine the measurement system to include absolute zero, so now you now have this really awkward 273.15... degree difference between the two scales, the nice scale that starts at zero has no other auspicious points to calibrate it at, and the scale with nice points does not start at zero. they could have made their new scale 100 degrees between zero and the freezing point of water, but that would have re jiggered every other derived unit, so understandable that they did not.
Personally I think an si system set up around base twelve would kick ass, what would make it even better would be to replace our base ten number system with a base twelve one, 10 is kind of a poor number in terms of fractions possible. 2 is fine but nobody wants to use 5, things just get awkward when you use 5. nether one is ever going to happen but it is fun to think about our assumptions when it comes to counting and measurement.
