*In the textbook these are presented as questions (e.g. "Use metric prefixes to express 10^6 phones", etc.) WITHOUT the answers. In the list above, the answers on the right side of each equals sign were suppied by me.

PS
One particular example caught my notice as I was typing these because it is similar to, but not the same as (and actually in contradiction to), one of those from the Edmonton list. The physics book gives:
10^1 cards = 1 dekacards
while the Edmonton article gave
52 cards = 1 dekacards
Actually, BOTH are wrong, although for different reasons. The physics book version uses the fact that the prefix "deka" stands for 10^1 (or just plain 10) so it says ten cards equals one dekacards (deck of cards). That's right as far as the use of prefixes is concerned but wrong from the standpoint of the actual number of cards in a standard deck (which is 52). The Edmonton article used the correct number for the number of cards in a deck, but, of course, then the prefix would be wrong because deka does NOT stand for 52, it stands for 10.
This is as good an example as any to show that this whole business is just silly (although fun) and should not be taken seriously. None of these "conversions" is really right or wrong; they are all just silly.
