Jul 30, 2024 · There are two ways to calculate total body water from weight: To estimate the body water content knowing that the average adult male is 60% of water, and average adult female - 50%. If you know a person's age and height, you can use P.E. Watson's formula. For males: TBW = 2.447 - 0.09156 × A + 0.1074 × H + 0.3362 × W. For females:

Male TBW = 2.447 - (0.09156 x age) + (0.1074 x height) + (0.3362 x weight)Female TBW = -2.097 + (0.1069 x height) + (0.2466 x weight)Male TBW = (0.194786 x height) + (0.296785 x weight) - 14.012934Female TBW = (0.34454 x height) + (0.183809 x weight) - 35.270121Boys TBW (height < 132.7 cm) = -1.927 + 0.465 x weight + 0.045 x heightBoys TBW (height > 132.7 cm) = -21.993 + 0.406 x weight + 0.209 x heightGirls TBW (height < 110.8 cm) = 0.076 + 0.507 x weight + 0.013 x heightGirls TBW (height > 110.8 cm) = -10.313 + 0.252 x weight + 0.154 x heightHow To Calculate Total Body Water? Total Body Water (TBW) can be estimated using various formulas tailored to different demographics. [1] Here are the commonly used formulas: Watson Formulas: For Men: TBW (liters) = 2.447 – (0.09156 × age) + (0.1074 × height in cm) + (0.3362 × weight in kg)
Total body water can be estimated using the following classic formulae: For males. Total Body Water (TBW) = 2.447 - 0.09516 X age + 0.1074 X height + 0.3362 X weight. Water in Litres; Age in years; Height in cm; Weight in kg; For females. TBW = -2.097 + 0.1069 X height + 0.2466 X weight. Water in Litres; Height in cm; Weight in kg
Watson formula. For males: TBW = 2.447 - 0.09156 × age + 0.1074 × height + 0.3362 × weight. For females: TBW = -2.097 + 0.1069 × height + 0.2466 × weight. where: age in years, height in centimeters, weight in kilograms. Interpreting your Total Body Water results.
Calculating Total Body Water. There are several methods for calculating the total amount of water in the body. In our Total Body Water Calculator we use the P.E. Watson’s formula, which is a widely used equation for estimating TBW. It takes into account a person’s body weight, height, age, and gender to provide an estimate of their TBW value:
