A: A unit of whole blood is 450 milliliters, which is about 0.9510 U.S. pint. For components of blood, one unit is the amount of that substance that would normally be found in one unit of whole blood. The adult human body contains roughly 12 units of whole blood.

Note: although the unit is defined by volume, it is actually measured by mass at blood collection centers. Since the density of human blood is 1.053 kilograms per liter, the mass of a unit of blood is about 474 grams or 16.7 ounces.

This depends on measurement of the unit. For an instance, 1 mm3 of human blood contains 4.5 - 5 million of red blood cells.
