Thanks guys. I found these formulas on the internet,

 

Calculation of internal heat production, H

(from McIntyre, 1980)

H (W.m-2) = (M x (1- h)) x 1/AD

where M = metabolic free production (W.m-2), h= mechanical efficiency and AD is the body surface area (m2).

 

I have all of the values but I don't understand the unit.(W.m-2)

(-2 is a superscript) Any help?

W is watt, i.e the unit of power (energy per unit time). I can't remember what 1W is in joules/second.

 

m^-2 is 1/(metres squared)

 

so it's power per unit area.

anyone else notice how chemistry teachers seem to care alot more about units than teachers in other scientific fields, including physics?

That's because in physics the teachers know that if they show the class what all the units are, some bright spark will figure out they're being taught lies in preparation for college/Uni.
