Understand your hydration levels by estimating your total body water percentage based on your age, weight, and biological sex.
Total Body Water (Liters):
32.592 L
Body Water Percentage:
47%
Typical ranges for healthy individuals are approximately 50-60% for males and 45-50% for females. This result is an estimate based on your provided physical data.
Total body water (TBW) is estimated using formulas like the Watson formula, which account for age, sex, and weight.
Formula (Simplified): TBW % = (Coefficient Based on Sex & Age) × Weight / 100
TBW % = (Coefficient Based on Sex & Age) × Weight / 100
Example for a 70kg male, aged 30, with an estimated TBW of 42 liters.
Water is critical for metabolism, nutrient transport, and temperature regulation. Percentage declines with age as muscle mass (which holds water) is replaced by fat.
This calculator provides estimates only. Actual hydration varies based on activity level, health conditions, and environment. Consult a professional for clinical concerns.
Men typically have more lean muscle tissue, which contains significantly more water than adipose (fat) tissue.
Checking once or twice a year is sufficient for tracking long-term trends, though daily hydration monitoring is better done via intake tracking.
