The Blood Volume in a Human calculator estimates the blood volume (BV) of a human based on their weight (mass).
INSTRUCTIONS: Choose units and enter the following:
- (wt) This is the weight or mass of the person
Blood Volume (BV): The calculator returns the volume in milliliters (ml). However, this can be automatically converted to compatible units via the pull-down menu.
Heart / Blood Calculators:
- Compute the Heart Chamber Pressure via the Law of Laplace
- Compute the Heart Wall Stress via the Law of Laplace
- Compute the Blood Flow Rate using Darcy's Law
- Compute the Change in Vascular Pressure
- Compute Blood Pressure
- Compute the Blood Volume in a Human based on their weight
The Math / Science
The volume of blood in a person is computed using the ratio of blood per kilogram (75 ml/kg). The formula for volume of blood in a human is:
BV = wt • bpk
where:
- BV is the blood volume of a human
- wt is their weight converted into kilograms
- bpk is the blood per kilogram
