"Hawaii" can't be used as a unit to measure distance, nor can "the equator", but "the distance from Hawaii to the equator" can. Similarly, "the difference between 0 orgasms and 1 orgasm" can be used as a unit to measure utilities (you could call this unit "1 orgasm", but that would be confusing and silly if you had nonlinear utility in orgasms: 501 orgasms could be less than or more than "1 orgasm" better than 500).

Also, did you mean to have these the other way around?:

but prefers 1/400 of being a whale to 1 orgasm
