Our free Body Fluid Calculator is an essential tool for healthcare professionals and individuals interested in fluid balance. Easily estimate your Total Body Water (TBW), Intracellular Fluid (ICF), and Extracellular Fluid (ECF) volumes. Understand your body's fluid distribution for optimal hydration and health assessment with this essential tool.
Formula:
The Total Body Water (TBW) is estimated based on body weight and gender. Intracellular Fluid (ICF) and Extracellular Fluid (ECF) are then derived from TBW.
- TBW (Total Body Water) ≈ Coefficient × Weight (kg)
- ICF (Intracellular Fluid) ≈ (2/3) × TBW
- ECF (Extracellular Fluid) ≈ (1/3) × TBW
Coefficient: Approximately 0.6 for adult men, and 0.5 for adult women. These are general estimations and actual values can vary.
