The size of the human brain in terms of weight the average adult human brain weighs in at 1300 to 1400 grams or around 3 pounds. It is a subset of cephalometry measurement of the head which in humans is a subset of anthropometry measurement of the human body.

Measurement of brain in human body. It is a symmetrical structure situated on top of the brain stem and on either side of the third cortex. Small samples of biological material are needed for the analyses and the results are comparable with the reference randox method. The adult human brain weighs on average about 1214 kg 2631 lb which is about 2 of the total body weight with a volume of around 1260 cm 3 in men and 1130 cm 3 in women. A human skull and measurement device from 1902. Conventional science and medicine have long used the electrocardiogram ecg and the electroencephalogram eeg to assess physiologic function of heart and brain respectively. In terms of length the average brain is around 15 centimeters long.
Craniometry is measurement of the cranium the main part of the skull usually the human cranium. The adult human brain weighs on average about 15 kg 33 lb. The brain is an organ thats made up of a large mass of nerve tissue thats protected within the skull. The raw brain to body mass ratio is however simpler to come by and is still a useful tool for comparing encephalization w. The average male has a brain volume of 1274 cubic centimeters. It plays a role in just about every major body system.
Brain to body mass ratio also known as the brain to body weight ratio is the ratio of brain mass to body mass which is hypothesized to be a rough estimate of the intelligence of an animal although fairly inaccurate in many cases. The heart produces coherent contraction of numerous muscle cells resulting in vigorous electrical activity. Conclusionsthis method is easy rapid reliable and practical for the routine measurement of total antioxidant activity in serum and other human body fluids. The volume is around 1260 cm 3 in men and 1130 cm 3 in women although there is substantial individual variation. There is substantial individual variation with the standard reference range for men being 11801620 g 260357 lb and for women 10301400 g 227309 lb. A more complex measurement encephalization quotient takes into account allometric effects of widely divergent body sizes across several taxa.
For comparison a newborn human babys brain weighs approximately 350 to 400 grams or three quarters of a pound. The human brain is the largest brain of all vertebrates relative to body size. It weighs about 33 lbs. In men the average weight is about 1370 g and in women about 1200 g. The two halves are bulb shaped and are about 55 to 60 centimeters in length in the average.
