How heavy is your brain?

qalinle asked:
What is the weight of the human brain?

The human brain will obviously vary between people but it is around 1.5kg (3lbs) (80% of which is water). On average, a woman's brain is 200g (7oz) lighter than a man's; this is due to the fact that men, on average, have bigger heads.
