All measurement systems are based on some sort of arbitrary convention.
Imperial is derided because of its legendary foundations as being based on a person's proportions.
Metric is equally arbitrary in being based originally on the
circumference of the earth. The French found to their dismay that the Earth was not as easy to measure as they had assumed. The meter now is based on the
oscillations of an atom of cesium-137. Anybody got cesium-137 in their fridge?
The point is, if a large enough group of people agree to use the convention, then it really doesn't matter if it is 'easier', 'or this system is superior', etc. Oil is still priced in barrels of 42 U.S. gallons, because a large enough number of people agrees to this convention.
In my work as an engineer, I use USCS and SI often, but I prefer USCS because I have worked with it long enough to gauge relative magnitudes easily. I don't particularly have a problem with the conversions, because they are just numbers.
I find that the number of SI derived units have grown like Topsy, and one needs a
dictionary to keep the constituent units straight. If SI were ever revised significantly, I would hope that the thicket of derived units could be pruned back, and that units with more practical magnitudes substituted for the current ones.
In these forums, you will continue to find students who struggle with SI even though that is all that they have ever known.
