Water Intake Calculator

How this is calculated

We scale a simple daily fluid target from your weight and an activity band (low / moderate / high). It is a planning heuristic, not a medical prescription.

Use this tool for

  • Setting a rough daily fluid goal before sports or travel.
  • Teaching how activity level scales simple hydration heuristics.
  • Comparing “how much water” ballparks between weight changes.

Common questions

What should I double-check before trusting Water Intake Calculator?

Confirm weight units (kg vs lb) and the activity level that best matches today; small changes there move the recommendation.
