Calculate your Liquid Consumption

Here you can calculate your average daily liquid consumption during normal activity and normal temperature. It is always better to drink a little more. Water and unsweetened teas (no black or green tea) are particularly suitable. Your water needs increase when you sweat, i.e., in high temperatures and during exertion. You should then drink more accordingly. This calculation only applies to adults; children need more water per kilogram of body weight!
Enter your weight in kilograms and click Calculate to determine your minimum water needs.

Weight (kg):
Liquid consumption (ml):

The calculation is as follows:
For the first 10 kg of the body weight take 100ml per kg.
For the next 10 kg of the body weight take 50ml per kg.
For the rest kg of the body weight take 15ml per kg.
Example of using this formula:
55 kg body weight
10 kg * 100ml = 1000ml
10 kg * 50ml = 500ml
35 kg * 15ml = 525ml
Average daily liquid requirement: (1000 + 500 + 525) ml = 2025ml, so a bit more than 2 liters.

Liquid here means water and water-based beverages. Other liquid substances such as alcohol or cooking oil are of course not included here. Drinks that can be fully counted towards your fluid needs are, of course, water, whether still or carbonated, then unsweetened tea or coffee without caffeine, fruit juice spritzers, and vegetable broths. Caffeinated beverages such as black or green tea and coffee, lightly sweetened drinks such as lemonades and juices, as well as non-alcoholic beer and milk can contribute to a limited extent. Alcoholic beverages, highly sweetened drinks such as cola, and very caffeinated drinks such as energy drinks, which are often also heavily sweetened, are unsuitable and in some cases even counterproductive. Foods that supply the body with water include many fruits and vegetables, such as melons, oranges, cucumbers, and tomatoes, as well as yogurt and quark.
