Almost, you scale by their metabolic weight. It's about 7 times higher for mice than for humans.
I'm not a scientist (heh) so the best explanation a quick google search gave was an article on CLA from the jn - journal of nutrition:
"The relationship between basal metabolic rate or energy expenditure and body weight in different size mammals is described by the function Y = aX0.75, where Y is basal metabolic rate (kJ/d), X is body weight (kg) and a is basal metabolic rate per kg0.75 per day, which is ∼300 kJ/ (kg0.75 · d). Thus, the basal metabolic rate in different size species is proportional to the body weight raised to the 0.75 power, the so called metabolic weight."
