Quick Answer: What Is The Weight Of Human Brain In KG?

How do you calculate brain weight?

The brain was weighed immediately after removal.

A residual analysis of the correlations between skull measurements and the true brain weight was carried out, resulting in the formula: brain weight, g = (21.8 x axial circumference, cm) + (13.9 x transversal circumference, cm) + (2.105 x length x width, cm) – 890..
