There's enough blood in the human body to fill a bit more than a 1-gallon milk jug. The average adult has about 1.2 to 1.5 gallons (4.5 to 5.5 liters) of blood circulating inside their body, said Dr. Daniel Landau, a hematologist and oncologist at the University of Florida Cancer Center – Orlando Health. If you had no blood, you'd weigh 8 to 10% less. (Of course, you wouldn't be alive, either.) So, for example, in a person weighing 120 lbs. (54 kilograms), blood takes up about 9.6 to 12 lbs. (4.4 to 5.4 kg).
