I think if forced, under considerable duress and on pain of death, you
could (on a good day) guess what was meant :-)

The problem with saying you consume 400W of electricity in one hour is
that there is instantly a corollary, which it that you will thus
consume 800W in two hours, and so on. Do you see the problem?
