Shown here is a depiction of a human brain beside a noticeably bigger elephant brain. The average human brain weighs in at around 3 pounds, and an elephant brain can weigh close to four times that much, but the biggest brains of all come sperm whales, and weigh an average of 17 pounds.
The adult human brain weighs on average about 1.5 kg (3.3 lb) with a volume of around 1130 cubic centimetres cm 3 in women and 1260 cm 3 in men, although there is substantial individual variation.n elephant 's brain weighs just over 5 kg (11 lb), a bottlenose dolphin 's 1.5 to 1.7 kg (3.3 to 3.7 lb), whereas a human brain is around 1.3 to 1.5 kg (2.9 to 3.3 lb). Brain size tends to vary according to body size.
