Baseline is ~33 ml per kg body weight, plus ~350 ml per 30 min of exercise and a climate bump. Caffeinated drinks still count as fluid, but each cup after the first adds ~200 ml to replace the mild diuretic effect.

Personalizes the common “2 liters a day” rule to your weight, adjusts for exercise time, climate and coffee/tea intake, and converts the result into practical 250-ml glasses or 500-ml bottles.
