About this tool
This page opens the water intake calculator with a body weight of 70 kilograms already filled in, no exercise added and a temperate climate selected — the plain reference case with none of the adjustments turned on.
At 70 kg, the ~35 ml-per-kg baseline works out to about 2.45 liters, or roughly 2450 ml, split into about 10 glasses of 250 ml across the day. That number is a starting point for a sedentary day in a mild climate — it is what your body needs just to function, before accounting for a workout or a heatwave.
70 kg is a commonly used reference weight, not your weight — the whole point of this calculator is that the number scales with the person. Swap in your own body weight, and the target recalculates instantly and privately in your browser; nothing you type is sent anywhere.
Example. A weight of 60 kg with no exercise and a temperate climate returns 2100 ml, 2.1 L, and 9 glasses of 250 ml.
Limit. Weight must be from 20 to 300 kg, exercise from 0 to 1440 minutes, and the additives are 35 ml per kg, 350 ml per 30 minutes, and 500 ml in a hot climate.
