Would you agree that the amount of energy passing a point
in a unit-time is power?

Or even more to the point: Do you believe the 'amount of motorcycle'
passing a point in a unit time is speed? :-)

The units speak plainly enough for themselves. Why do you ask me?
You're the one who always turns these things into a religious argument
over 'belief' systems.
