The calculator uses a modified version of the Watson formula for estimating Total Body Water (TBW). This formula accounts for age, height, weight, and gender for a more accurate estimation.
For Men: TBW (Liters) = 2.447 - (0.09156 × Age) + (0.1074 × Heightcm) + (0.3362 × Weightkg)For Women: TBW (Liters) = -2.097 + (0.1069 × Heightcm) + (0.2466 × Weightkg)
Where:
- TBW: Total Body Water in Liters
- Age: Age in years
- Heightcm: Height in centimeters
- Weightkg: Weight in kilograms
