How many times more than the brain does the human body typically weigh?

Since there is a huge difference in weights, it is quite difficult to answer this question. Americans being too fat, if you consider an average weight of 70kg for Western European adults, and a weight of kg 1.4 for the brain, the ratio amounts to 50 times. http://faculty.washington.edu/chudler/nsdivide.html [Link added -- Zb] Aug 11 00, 9:57 AM

Additionally, the newborn human brain weighs in the neighborhood of 350g - 400g, substantially changing the ratio. Although the mass of the newborn's brain is about 25% of its final adult brain mass, the mass of the newborn's body is only about 5% of its adult mass. Adult human brain: 1,300g - 1,400g Adult: Percentage brain of total body weight (150 pound human) = 2% http://faculty.washington.edu/chudler/facts.html http://www.hypertextbook.com/facts/2002/LeahOppenheim1.shtml Apr 06 08, 5:20 PM
