This online calculator is used to find the quantity of water present in human body.
Total Body Water (TBW) is the total amount of water present in the body in the form of body fluids, tissues and organs. In a broad way, water content is a human body is divided into two types; intracellular fluid and extracellular fluid. Intracellular fluid is the water stored inside the cells. It constitutes about two third of the total body water content. Extracellular fluid is the water stored and flowing outside the cells. Extracellular fluid constitutes about one third of the total body water. An average female adult human body contains 50% of water and a male adult body contains 60% of water. But this amount varies based on various factors like height, weight, age, disease, etc...
There are several formulas to calculate the total body water content. The popular and most used ones are the formulas put forward by:
TBW-W (for Male) = 2.447 - (0.09156 x A) + (0.1074 x ht) + (0.3362 x wt) litres
TBW-W (for Female) = -2.097 + (0.1069 x ht) + (0.2466 x wt) litres
TBW-H (for Male) = (0.194786 x H) + (0.296785 x W) - 14.012934
TBW-H (for Female) = (0.344547 x H) + (0.183809 x W) - 35.270121
TBW-C = H x (0.0186104 x W + 0.12703384) + W x (0.11262857 x M + 0.00104135 x A - 0.00067247 x W - 0.04012056) - A x (0.03486146 x M + 0.07493713) - M x 1.01767992 + D x 0.57894981
