Hume and Weyers developed equations for predicting a person's total body water (TBW) from the gender, height and weight.
Parameters:
(1) gender
(2) height in centimeters
(3) weight in kilograms
For males over 16 years of age
total body water in liters =
= (0.194786 * (height in cm)) + (0.296785 * (weight in kg)) - 14.012934
For females over 16 years of age
total body water in liters =
= (0.344547 * (height in cm)) + (0.183809 * (weight in kg)) - 35.270121
