    Metabolic rate scales with the mass of an organism of a given species according to Kleiber's law where B is whole organism metabolic rate (in watts or other unit of power), M is organism mass (in kg), and B o is a mass-independent normalization constant (given in a unit of power divided by a unit of mass. In this case, watts per kilogram):
