About this water intake calculator

  • Base calculation: 35ml per kg body weight (standard clinical guideline)
  • Activity adjustment: +250ml (light) to +750ml (heavy exercise)
  • Climate adjustment: +200ml (moderate) to +400ml (hot & humid) — India-specific
  • Caffeine offset: ~125ml per cup of chai/coffee to compensate for diuretic effect
  • Pregnancy (+300ml) and breastfeeding (+700ml) adjustments per WHO guidelines
  • Results are estimates — individual needs vary. Urine colour is the best real-time indicator
