Hi gurus.

Hopefully this should be an easy one : I am having

trouble finding the correct word, in English, to describe

a simple equation, concerning Energy, Power, and Time:

Power = Energy or, with units: Watts = Joules

------ ------

Time Seconds

So how do you explain the term 'Power,' in English, to the layman? The answer of course, Energy divided by Time, is expressed in English typically as "the **RATE** of expenditure of energy." So far so good.

But what if we want to use a common English term to describe Energy in terms

of power ?

So, turn the equation around and we get :

Energy = Power * Time

So if Energy equals Power multiplied by Time, what is the elegant

way of expressing this multiplication-by-time relationship in English?

"Divided by Time" becomes "Rate" in the first example. This is because

the word 'rate' means, not 'division,' but 'division by time.'

What can I use as a substitute for "Multiplied by Time?"

please don't suggest "product" as this word is nothing to do with Time

as a quantity, unlike the word 'rate.'

I need an English word that conveys the meaning of this multiplied-by-time relationship, not just an alternative word for "multiplied by."

My only guess so far is 'time-spread.'

Basically, I want to say something like this:

Energy is the 'time-spread' of power, or with units,

"One Joule is the time-spread of power."

There must be an official English word for this, used in science.

In maths, the terms are just joined with a hyphen:

1 joule = 1 watt-second

pronounced

"one joule equals one watt second."

However this does not convey anything like the same meaning

as the word 'rate' does for 'divided by time.'

help!
