Here's an answer:
The brain is about 3 lbs. Read More
The size of the brain is usually measured in weight or volume. The average adult human brain weighs between 1300 g and 1400 g (approximately 3 lbs). A newborn human brain weighs between 350 and 400 g. For a 150 lb adult, the brain is 2% of the entire body weight.
Men typically have bigger brains than women, approximating a volume of 1130 cubic centimetres (cm3) for women and 1260 cm3 for men.
Over the course of human evolution, brain size tripled as early humans faced new environmental challenges. Today, the human brain is the largest and most complex of any living primate.
