Body Fluid Compartment Calculator
TBW (Total body water) = Body weight × 60%
TBW = ECF + ICF
ECF (Extracellular fluid) = TBW × 1/3 = Body weight × 20%
ICF (Intracellular fluid) = TBW × 2/3 = Body weight × 40%
ECF = Plasma + Interstitial fluid
Plasma = ECF × 1/4 = Body weight × 5%
Interstitial fluid = ECF x 3/4 = Body weight × 15%
