Where 35 ml comes from
The page uses 35 millilitres per kilogram of body weight. That is a common rule of thumb, not a measured need. Food, climate, illness and medical conditions change what a person should drink. The exercise line adds a flat 350 ml. It does not know how long you trained.
Cups on this page are 240 ml. A kitchen cup in a recipe can differ.

Questions
Does coffee count?
