Inconsistencies in the SI, retained for the sake of tradition and for "avoiding" confusion, do exist and make the adoption of SI far from straight forward. For example, prefixes over 1 are supposed to be symbolized by capital letters. But not the kilo where K stands for kelvin. Confusing. So are symbols for deka a hekto inconsistently the lower case. And the worst of all is the kg, a base unit with a prefix. It is a shame that inconsistency was not fixed with the changeover to SI. Metric people, of course, are long used to it and most do not even learn the SI rules for writing in the first place. Stan Jakuba
