About blood volume calculation

Select your gender, enter your height and weight, and click the "Calculate blood volume" button to calculate your blood volume using Nadler's formula.

Also, a simple way to calculate blood volume is that blood is approximately 1/13 of body weight.

For example, if a person weighs 65 kg, 60 ÷ 13 = 5 kg.

Blood volume calculation formula

Blood volume is calculated using Nadler's formula below.

Nadler's formula

Male: Blood volume(ml) = 0.3669 × H³ + 0.03219 × W + 0.6041

Female: Blood volume(ml) = 0.3561 × H³ + 0.03308 × W + 0.1833

Where
H = Height(m)
W = Body weight(kg)
