Ok, yes... e-6 (or, in J, e_6) as a suffix on a number means that that number includes a *&(10^_6) modifier (on the part which appears to the left of the 'e') which is equivalent to a %&1000000 modifier.
Similarly, for e-3. But when you change the modifier which is a part of the number you need to make the opposite change on the numeric part being modified, or the number which you are naming will not be the same number that you were talking about. So we could say "Multiplying the 'divided by 1000' aspect of the 'milli-' modifier in milliseconds gives you units of 'seconds'", but obviously when we do this we need to divide the numeric value [milliseconds] by 1000 if we want to represent the same interval of time.
