is this translation or localization ? One must remember that they are weighted in pounds (Avoirdupois) - that has 16 ounces. If you divide by two, it means that the baby will need per day an amount of water that is 1/32 of his weight. If you go metric, you must first decide if you express the water in liters (=kg) or milliliters ( = grams), then localize to something like. If milliliters, you may say 31.5 per kg of weight (3.15 is 1000/32). Accidentally, 32 is very close to 31.6 (square root of 1000) so division of 1000 by 32 is very close to 32.
