Daily Water Intake for 70kg: How Much to Drink
Estimate how much water you should drink a day from your weight, exercise and climate — in liters, milliliters and 250 ml glasses, right in your browser.
Result
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.
