The best thing about SI is that it only has one unit per dimension, and no conversion factors between units (it is "coherent"). Unfortunately, this simplicity and elegance usually goes unappreciated; while people focus on arbitrary powers of ten (e.g. that 100 hundredths is one)
PS: The SI unit of time is the "second"; which is actually a sexagesimal fraction (a "pars minuta secunda", AKA a second small part; which is a sixtieth of a "pars minuta", a sixtieth of an hour)
