My Human Physiology book says that the 70-kilogram (154 pounds) reference man has 60% of his total body weight in the form of water (42 kg or 92.4 pounds). For women, it's a bit less because women have more adipose tissue (fat). Infants have more and old people have less water.

About two thirds of the water is in the cells, and the remaining third is split between interstitial fluid (75%) and the (blood) plasma (25%).
