I think "1 hour’s worth" is the correct way to write this. Therefore, in the plural case, I assume the correct choice is "2 hours’ worth". Which one is it?

Just wondering because someone edited a question of mine to remove these apostrophes.

You are correct. There is no logical reason for the number (not case) to be plural with one. It's like saying a worth of one hour, so the genitive (aka possessive) case would be correct.

In what way have I misunderstood? – Brett Reynolds Apr 21 '12 at 12:15
Maybe you didn’t misunderstand it, it’s just that this is not about whether it should be singular or plural. Your second sentence addresses only the number, and the last sentence seems to assume singular. But the question is about which case to use in the plural :) – Timwi Apr 21 '12 at 12:17
But I didn't answer whether it should be singular or plural. I answered whether it should be bare or genitive. The use of the singular simplifies things, as the OP clearly realizes. – Brett Reynolds Apr 21 '12 at 12:19
OK, then I’m the one who misunderstood :) My apologies :) – Timwi Apr 21 '12 at 12:22
