Frequently Asked Questions
How is daily water intake calculated?
Daily water intake is calculated based on body weight (35ml per kg as baseline), exercise duration (+350ml per 30 minutes), environmental factors (hot/humid or high altitude conditions add 10% each), and special conditions like pregnancy or breastfeeding.
Do exercise and heat increase water needs?
Yes, exercise increases water needs by approximately 350ml (12 fl oz) per 30 minutes of activity. Hot, humid, or high altitude environments each increase needs by 10% due to increased fluid loss.
Should pregnant or breastfeeding people drink more water?
Yes, pregnancy typically requires an additional 300ml daily, while breastfeeding requires an additional 700ml daily to support increased physiological needs.
Can I view results in liters or ounces?
Yes, the calculator displays results in multiple units: liters (L), fluid ounces (fl oz), and cups. You can toggle between metric and imperial displays.
