How much fluid should you drink in a day?
Diane K Newman, RN-C, MSN, ANP posted:
A formula for calculating proper fluid intake (in the absence of fluid restriction, and with normal physical activity and moderate temperatures) based on body weight can be calculated in three steps. Before doing the calculation, body weight must be expressed in kilograms (2.2 lbs equals 1 kilogram):

1. For the first 10 kg, the fluid requirement is 100ml/kg or 1000ml (4.23 cups)
2. For the second 10 kg, the fluid requirement is 50ml/kg or 500ml (2.11 cups)
3. For weight over 20 kg, the fluid requirement is 20ml/kg (20 ml = .08 cups)
