The weight of whole blood at body temperature is 2.315 lbs/liter.
This number was calculated as follows:
Specific density of blood = 1.0506 that of water.
Water weighs 62.4 lbs/ft3.
So blood weighs 62.4 x 1.0506 = 65.56 lbs/ft3.
1 ft3 = 0.02832 m3
So multiplying 65.5 lbs/ft3 x 1 ft3/.02832 m3 = 2314.9 lbs/m3
1 liter = 10-3 m3
Therefore 1 liter of blood weighs 2.3149 lbs.
A human weighing 40 stone would have 8 to 10 pints of blood.
Blood makes up 7% of the weight of the body in humans. See: http://en.wikipedia.org/wiki/Blood
blood volume
blood volume
Blood accounts for about 8% of the human body weight. The average adult has a blood volume of about 5 liters (1.3 gallons).
The amount of blood a human has is generally correlated with body size, including height and weight. On average, an adult has about 7-8% of their body weight in blood, which means taller and heavier individuals typically have a greater blood volume. For instance, a person weighing around 70 kg may have approximately 5-6 liters of blood, while a larger individual would have proportionately more. However, individual variations, such as health status and fitness levels, can also influence blood volume.
Human hemoglobin makes up approximately 96-98% of the dry weight of human blood.
blood volume
The average blood volume in an adult human body is around 5-6 liters. This can vary based on factors such as age, weight, and gender.
On average, a human adult has about 1.2 to 1.5 gallons (4.5 to 5.5 liters) of blood in their body. This is roughly 7-8% of their total body weight. Blood volume can vary based on factors such as age, weight, and gender.
It depends on the person and their age. It contains about 5.6 liters or 6 quarts of blood.
In an adult human has 5.0-6.0 lt of blood pH IS 7.4, about 7-8 percent of body weight.
