What is a Watt???

[Derek]

Where is Climate Realist when you need him....
I AM WRONG, in my first point in post 47,
there is a hidden time term of one second in a Watt, and a W/m2.

A pint of beer is just that, a volume or an amount of beer.
However, if you pour a pint of beer onto the floor in a second then you have a flow, a rate, power.
So, a power figure has to be an amount over an amount of time.
For example a bhp also has a hidden time term of a second in it.
Let us say we have a 100bhp engine that burns 10 liters of fuel in 100 seconds.
That would be 100bhp 0.1 liters of fuel.
Does that make sense???
No.

How about, 100bhp per 0.1 liters of fuel per second, now that makes sense.
Power is an amount spread over a time period, which in the SI system is usually one second.
Later addition - The time period HAS TO BE a second because,
anything ties or divided by 1 is the same number.
This means that a timeless power figure divided over a second (averaged) is the same.
That makes sense, that means it can be used to calculate / compare with.
IF the power figure was "timeless" then you could not compare / calculate.
QED - All power figures, by default, because of the mathematical "quirk" of one, have to have (or are rather an amount of work averaged over) a second in them.

It does make me wonder what RTF was trying to do here in his posts???
