Biology Question: Why do scientists have 2 possible formulae ...

Why do scientists have 2 possible formulae for calculating brain mass? 1) b=0.01m^2/3 2) b = 0.01m^0.7 b = 0.085m^0.66 -------This is for calculating human brain mass from their total mass. b = brain mass (usually in kilogram) m = total mass (in kilogram) ^ = exponent sign Does anyone know? some say 1st formula is correct, others say 2nd is. Weird...

Possibly because the formulas are not really that accurate and so some just round 2/3 to 0.7 since 2/3 is 0.6666666666. As far as the 0.01 or 0.085 constant on the front that is a bigger difference but again maybe the accuracy is not great. Don't know if I helped or not gorgeous.
