Doctors generally use this formula when calculating the body’s water needs.
4 ml per kilogram for the first 10 kilograms of our weight
2 ml per kilogram for the next 2nd 10 kilograms
For each subsequent kilogram, 1 ml of water per hour is added.
That is, for a healthy person of 67 kilograms, for the first 10 kilograms, 10×4=40ml,
for the second 10 kilograms, 10×2=20ml
for the remaining 47 kilograms, 47×1=47ml
In total, we should drink 40+20+47=107 ml of water per hour.
Daily, it is 107×24=2568ml
