Just a random thing I realized that makes the names in the metric system a bit better is that no matter what the type of unit, the different sizes have the same names. In metric, you have a meter, and you put the different prefixes on it to make the centimeter, the millimeter, kilometer, etc. In Imperial, you just have several unrelated words, inch, foot, yard, mile, etc.
But, in another area, let's say volume, you have the liter in metric. You put the same prefixes to make centiliters (which I've never heard of), milliliters, kiloliters, etc. Now, in the Imperial system, you have to memorize several new words, the ounce, the cup, the pint, the quart, etc.
In the end, there's less words to memorize as in metric you just memorize one word for each type of unit (and a few prefixes that apply to all units), where in Imperial, you have several words to memorize for each type of unit.
