Mathematical Formulas & Calculation Methods

Daily Hydration Requirement Formula

Standard rule: drink 35 mL of water per kg of body weight (or 0.5 to 0.6 oz per pound), plus 12 oz (350 mL) per 30 minutes of exercise.

Base Water (Liters) = Body Weight (kg) × 0.035 + (Workout Mins ÷ 30 × 0.35)

Worked Step-by-Step Examples

Example 1: 70 kg Person exercising 45 Minutes Daily

"Calculate daily water requirement for a 70 kg person doing 45 minutes of daily exercise."

Steps:

Base water requirement: 70 kg × 0.035 L = 2.45 Liters
Workout bonus: (45 / 30) × 0.35 L = 0.525 Liters
Total daily target: 2.45 + 0.525 = 2.975 Liters (~100 oz)

Result: Recommended Daily Water: ~3.0 Liters (approx 12 glass cups).
