How many pints of blood does the average adult body have?

Blood volume scales with body size and is about 7–8% of body weight. For an average adult, that amounts to roughly 5 liters of blood in circulation. Since a pint is about 0.473 liters, 5 liters is around 10 pints. So the typical adult body contains about 10 pints of blood. Variations exist with size, sex, and health, but 5 liters/10 pints is the standard reference. The other options would correspond to notably smaller or larger volumes than what's typical for an average adult.
