No. Like said my equation was:
2000Cal/1day
http://www.wolframalpha.com/input/?i=2000Cal%2F1day
And to prove I can do this on my own:
2000Cal / 1day = (2000000*4.18) J / (24*60*60) s = 8360000J / 86400 s = 96.76 J/s = 96.76W 🙂

I've got a question.
Are we doing your homework for you? Are you watching the National Geographic channel, but have no friends to ask when the show you're watching inspires a question?
Okay, I've got 2 questions for you.
If a tree falls in the woods on a planet where there is an atmosphere but the animals have no ears, does it make a sound?
3. I've got three questions for you.

Spread that heat energy over a much larger volume and I posit that a human body puts off more heat than a 100 watt (classic filament style bulb) light-bulb.
In fact, the human body may put off much more.
This could be done, easily...just hafta find out how hot the filment is, it's mass, and then, calculate the energy.
Then apply the same to the human body...
**** that. Too much effort.
1888 kcal/day * 4.18 kJ/kcal * 1 day / 8.64e4 sec = 91.3 Watts
So ~100W seems to be a good ballpark figure for a human body's power output.
