Your abject ignorance of algebra in particular and mathematics in general does not detract from the fact that you still haven't produced a definition of "kwh" - a term which YOU introduced and I did not.

Anyone who has paid attention understands clearly that you probably looked this term up and, discovering what it means, are lack the intellectual integrity to acknowledge that you were wrong.

are you talking about the 50,000 watt = 50kWh?
if so then I have already corrected that , would you mind correcting yours.

by admitting that you were wrong about your rants about
square area being exactly the same as squared area.

remember the stuff that you actually had to email your doctor about to ask him if you were wrong.

Quote:
when I wrote 50,000 watts it was not correct , the total watts was 180,000,000 watts because there are 3600 seconds in an hour.

so in 50 hours

50 * 3600 = 180,000

1000 watts * 180,000 seconds = 180,000,000 watts

which is 50 kWh if 1kW is used for 50 hours.

and to describe that I also used 50kWh

so I admit that that was wrong but the 50 kWh was correct.

but I wonder why such a brilliant algebraist or kallog never did correct that ?

strange

I certainly wouldnt ask you what its definition is and mostly I look up definitions in books and the internet , you wouldnt believe me if I told you so.

why dont you look it up yourself?

you do have the internet dont you?

1000 watts * 180,000 seconds = 180,000,000 watts = 50 kwh?


No amount of watt-seconds can ever equal any amount of watts.

Nor can any amount of watts ever equal any amount of kwh.

Algebra is not necessary to understand this.

I did not say I was wrong. I said I could be wrong. Not the same thing. Or is English another subject that you fail to grasp? Dr. Math has not yet responded to my email. YOU were the one who initially consulted him - as he was the primary reference on the wiki page that you first mentioned.

You have said a lot of stuff, but you have NOT answered the question I actually asked - the same question many times. What does "kwh" mean? What does it stand for?

whats the definition of watts?
whats the definition of watt-seconds?

The watt-second is the energy equivalent to the power of one watt sustained for one second.

your too stuck up on units , they dont always stick together the way you and algebra imagine them to.


1000 watts * 180,000 seconds = 180,000,000 watts

you dont need to tag seconds in the answer unless your a unit freak , its a worthless tag that only requires more typing.
and watts already has time included in its definition.

180,000,000 watts = any way you want to use it.

You're asking me a definition of a term that you first used, when you have steadfastly refused to provide one for another term that I have requested?

Talk about nerve!

A watt is a unit of power (rate of work production or conversion) equal to one joule per second (J/s). In electrical systems, this is the same as the rate of work produced by 1 amp across 1 volt. (P = VI)

Now, can you tell us what "kwh" stands for?

That is not a link to a homepage. It's a link to a google search.

According to the first definition that pops up under google (wiki),

"The kilowatt hour, or kilowatt-hour, (symbol kW·h, kW h or kWh) is a unit of energy equal to 1000 watt hours or 3.6 megajoules."

Do you agree with this?

I must be off for now.
but I will read your post later , Im sure it is important to
you that I read it and I intend to read it but there are things more important for me to accomplish at this time.

YES I AGREE STRONGLY WITH THAT

Why did it say watt hours and then say that it is equal to joules?

notice it did not say joule-hours !!!

which Im sure your algebra would have a fit with that.
but what would you expect from a worthless meaningless
course of study.

Wrong !!
3.6 MegaWatts does equal 1kwh.

Inversely, one watt is equal to 1 J/s.


Why didnt it say 1 watt/second is equal to 1 J/s

why would 1 watt equal 1 joule per second?

because time is included in the definition of a watt !!!!

you dont have much of a sense of time or the logic involved when dealing with units that have time built into them.

and just in case your still wondering here is the definition of joule

notice a unit of joule does NOT include TIME
but
units of watts do !!!!

go put that in your wolfram , LOL

it DOES NOT say that watts are equal to any amount of joules.

That's not what it says. It compares WATT-HOURS to joules, NOT WATTS.

To seal the deal that you can't read English?

Not inversely. 1 w = 1 J/s, period.

You've missed the entire point.

because 1 W/s <> 1 J/s, because 1 S <> 1 J.

Because 1 W = 1 J / s.

I suppose you think that is is logical to claim the below

No, it is relevant

because you try to change things that are established facts
in order to make your mistakes appear like you were right.

that type of behavior has no place in math or science and especially engineering.

Quote:

ANY amount of watts?

how about an amount of 3,600,000 watts?

because that equals 1 kWh.


and time is built into watts.

so if I used the 3,600,000 watts in 1 second I would have used 1 kWh of energy in that 1 second.

even if I dont use the 3,600,000 watts I still have 1kWh stored up to use as I please.

I could use the 1kWh in .00000000000001 seconds and I would have used up 1 kWh.

or I could use it in 50 years and I would have used up 1 kWh.


just the fact that its there means that I have 1kWh

its obvious that you dont even believe what you write yourself

why dont you stop selling yourself short and start reading up on what your posting about before you post about it.


Its getting really old having to correct your mistakes.

this is most likely why students have such a hard time LEARNING the CORRECT way to do math.

because the algebra has already compromised their logic and they cant even conceive that time can be built into a unit because algebra tells them that they must multiply everything even the units that dont even have a value.

idiotic wasteful stupid illogical algebra.

I have no use for it because it causes people such as yourself to make so many mistakes and mistakes cause buildings and bridges to fall down just like I make you fall down every time you make a post.


the only reason you fall is because of algebra.

it is flawed.

No where in that article does it claim that 1 kwh = 3,600,000 watts. One is a unit of energy, the other a unit of power.

Kilowatt-hour means "kilowatt times hour."

The knowledge of algebra has never made a building crumble. You're just making [censored] up.

Nearly every post you make illustrates your magnificent ignorance.

A heater rated at 1000 watts (1 kilowatt), operating for one hour uses one kilowatt hour (equivalent to 3.6 megajoules) of energy.


therefore

1000 watts used for 1 hour = 1 kilowatt hour
or
3,600,000 watts = 1 kilowatt hour

you must be reading another page !

I found it really quickly

if what you wrote above does not mean what it says then what does it really mean?

1) Nor can any amount of watts
2) ever equal
3) any amount of kwh

1) an amount of 3,600,000 watts
2) equals
3) 1 kWh

thats pretty clear and straight forward.

I think you think that a kWh must be used in 1 hour
but that would be wrong.

think about your electric bill , and kilowatt hours are units of billing of electricity , you might use only 1000 kWh per month , during the month.

a single light bulb that uses 21 watts will use
21 watts * 3600 seconds per hour
which would be 75,600 watt-seconds per hour or 75.6 kW per hour or 0.021 kWh

using algebra try the following equation
I wont attempt it because Im not a algebrain

1kW * 1 hour = ?

in reality it is possible to use 3,600,000 watts in 1 hour

suppose you are changing the heaters out for a large complex that uses 3,600 electric heaters and you need to know how much electricity they will draw in order to ensure that your emergency generators can handle the load if they are all turned on because you want to make sure that the generator will not feel to much of a power surge and shut itself down because of its overload protection.

not counting all other electricity draws except the heaters and also not counting the initial surge.

knowing that the heaters will use a total of
1000 watts * 3600 seconds * 3600 heaters each hour of use

12,960,000,000 watts per hour

1) would you need a 1kWh generator?
2) would you need a 3,600,000 watt generator?
3) would you need a 12 gigawatt generator?

False. Nothing in the article says that. kWh is a unit of energy. watts is a unit of power.

1 kWh = 1 kilowatt-hours which means 1 kilowatt times 1 hour = 1000 * 1 watt * 1 hour

And guess what - watts ALREADY have time units in them! AND YET ... there we have the kWh! Conclusion: whether something "already" has time units in it is irrelevant to the math that you do to it.

You're spouting nonsense. Take a basic science class.

Yes its because kilowatt hour (kWh) is not a unit of power
it is a unit of energy equal to 1000 watt hours or 3.6 megajoules.

a kilowatt hour and watt are not the same things
they are two separate units.

a watt is a unit of power not energy.
The unit, defined as one joule per second, measures the rate of energy conversion.

energy is measured in joules, but in many fields other units, such as kilowatt-hours and kilocalories, are customary. All of these units translate to units of work, which is always defined in terms of forces and the distances that the forces act through.

1000 watts used for 1 hour (is equal to) 1 kWh

do you understand that the above 1000 watts is power not energy.
but if you use 1000 watts for 1 hour it is equal to 3.6 mega J and it is also equal to 1 kWh

3.6 mega watts can be used in 1 second or
it can be used in 1 hour , watts per unit of time is energy.

The watt-second is the energy equivalent to the power of one watt sustained for one second.

so it just depends on the amount of time that your going to use the watts.

any amount of watts can be equal to an amount of kilowatt hours...

this is why your statement below is false

Quote:
Nor can any amount of watts ever equal any amount of kwh.


was that another typo were you asking
"or can any amount of watts ever equal any amount of kwh"
and the N was the typo?

In symbols, 1kWh <> W

Also correct.

Also, 1 Wh <> 1 W (one watt-hour does not equal 1 watt)

Also, 1 kWh <> 1 kW (one kilowatt-hour does not equal 1 kilowatt)
