A typical human body contains approximately a gallon and a quarter, or ten pints, or 4.7 liters of blood.

Consensus on the internet is that an average adult male has about 5.6 litres of blood in their body (one litre is a large-size Coke bottle).

See the links below for more info.

Hope it helps!

It all depends on how much you weigh. If you were 154 pounds per say you would have about 5.5 quarts of blood. So you can't just ask a dumb question and expect a good answer. (Even though this answers your question in way).

For a person weighing approximately 150 pounds, the blood volume is on average about 5 liters or 8.8 pints. If the person is larger or smaller, the blood volume would change accordingly. One liter of volume equals 1.76 pints.I hope this addresses your question.

it depends on the size of the body - bigger people have more blood.  So the only answer can be proportionate - i.e. X% of the human body is blood. I found a source which says about 7%.

We know that humans are about 70% water, but that fluid is not just blood - every cell is a little liquid pouch.  The amount of fluid in the vascular system is probably around what the prior responders state.

But, for example, a pregnant woman's blood volume increases by a third toward the end of the pregnancy - that's not counting the blood that the fetus itself made.

So the answer is a confident "it depends", but AFAIK, loss of more than three pints is life threatening.
