Scaling Laws

By Alex Denne

Mathematical relationships describing how properties change with size. Many biological and organizational properties scale predictably with organism or company size.

Foundations Metabolism and Burn Rate

"... Wrong. Kleiber found that metabolic rate scales with body mass to the 3/4 power. This is now called Kleiber's Law, and it's one of the most robust scaling laws in biology. The formula is: Metabolic Rate = M^0.75 Where M is body mass. What does this mean in practice? An animal that weighs 1,000 times m..."

"...overed that metabolism doesn't scale with mass (M^1.0) but with mass to the 3/4 power (M^0.75). This became Kleiber's Law—one of the most fundamental scaling laws in biology. Kleiber's Law: Basal metabolic rate (BMR) scales as mass^0.75. This means: - 1 kg animal: ~10 watts - 10 kg animal (10× mass): ~56 watts..."

Biological Context

Metabolic rate scales with body mass^0.75. Lifespan scales with mass^0.25. Heart rate scales with mass^-0.25. These relationships hold across enormous size ranges, suggesting fundamental constraints on biological organization.

Business Application

Business scaling laws describe how costs, revenue, and efficiency change with company size. Understanding these relationships helps set realistic growth expectations.
