How many watts does the sun equal??

[Hypertek99]

Is this a good question???

[JetCat USA]

174 petawatts

a pita is 10 to the 15th or a quadrillion or a thousand billion.

Our star has a luminosity of 3.85 x 10 to the 26th power watts, and yes that's an excellent question. TinMan

Can you type this out please?

Is'nt a thousand billion= trillion?
thousand million=billion
thousand billion=trillion
thousand trillion=quadrillion and so on.............

Would T-5 be close enough or would I have to go with MH?

"The Earth receives 174 petawatts (PW) of solar radiation at the upper atmosphere. While traveling through the atmosphere, 6% of the incoming solar radiation (insolation) is reflected and 16% is absorbed. Average atmospheric conditions (clouds, dust, pollutants) further reduce insolation by 20% through reflection and 3% through absorption"
"Atmospheric conditions not only reduce the quantity of insolation reaching the Earth's surface but also affect the quality of insolation by diffusing approximately 20% of the incoming light and altering its spectrum."

So the first 45% (6% reflected + 16% absorbed + 20% conditional reflection + 3% conditinal absoprbtion) brings the 174 petawatts down to 119 petawatts. Then 20% of that has had its spectrum altered. I guess this is still light thats reaching the tank, but even if we take that out of the 119 petawatts, we still have 95.2 petawatts at the very least.

95,200,000,000,000,000,000,000,000 watts

I have too much time on my hands...

10 (15) = 1,000,000,000,000,000 quadrillion 1,000 (1 + 4) thousand billion (or billiard) 1,000,000 (2.5)



Quad = four

So so are saying that a thousand billion is NOT a trillion.................
bi=two
tri=three
quad=four

a thousand billion is 10 to the 15th, a trillion is 10 to the 12th

Whichever one you get, make sure it comes with a polar icecap to cool it.

Uhh.... no

PAR Readings
Oklahoma sun at 5pm at street level: ~1800
4x 54w T5HO with individual Reflectors at water surface: ~300-500 depending on bulbs/ballast
1x 250w SE Metal Halide: ~200-400 depending on bulb/ballast

A thousand billions is not 10^12th (one trillion) ??

1,000 * 1,000,000,000 = 1,000,000,000,000
10^3 * 10^9 = 10^12

or what am I missing here? Are we confusing the British 'Thousand Billion' unit with the American equivalent of 'one thousand billions' where a British billion is 10^12 making a 'British Thousand Billion' 10^15? I think now even the American system is being used by the British government.

I'm on lots of cold medicine, but you lost me.

This post you mean? It looks like you just looked at the right hand side of your chart (british system) to define a 'thousand billion' and then the left hand side to define a 'trillion'. In that case, 10^12 (one trillion american) = 10^18 (one trillion british)? Spell it out for me -- I'm on lots of nyquil.

[JetCat USA]

a peta is 10 to the 15th or a quadrillion or a thousand billion, that covers American, European, Asian, African, Australian, etc....

[Salamander]

So, how many candle power is that?

How many 60 watt incandescent bulbs does the equate to?

[Salamander]

Hey Hyper...

Not sure if you're a VT fan but, GO HOKIES!!!!!!!!!

[JetCat USA]

candlepower isn't watt related, it's very different dependent on the type of light. Watts in that instance is a measurement of input and candlepower is a measurement of output.

Kinda:

Yes, a peta (SI) is 10^15th, or:

1. American: 1 quadrillion, or one thousand trillions
2. British: 1 thousand billion, or a 'billiard'

T Man's question was right on. Though we wouldn't use the term 'Thousand Billion' in America very often, we would equate it to a thousand billions (just the same way the British would, except they define a billion differently as 10^12 hence a 'thousand billion' being 10^15) which is an American 'trillion'.

Thank's cd77......I knew I wasn't losing my mind. Keep on drinkin' the Nyquil I shouldn't have "rolled over" so fast- That chart is just way too confusing for this ol' Tinner ! TinMan
