Calculation Method
Water needs vary based on body size, activity, and environment. We use 33ml per kg of body weight as the base.
Why 33ml/kg?
"The European Food Safety Authority recommends 30-35ml per kg for adults."
The Formula
Base = Weight (kg) × 33ml
Adjusted = Base × Activity × Climate
Activity: 1.0 - 1.5×
Climate: 0.95 - 1.2×
