How to use
- Enter body weight and choose kg or lb.
- Select the day type and climate that best match the day you are planning for.
- Use the result as a daily hydration checkpoint, then move to Sweat Rate for a session-specific check, to Dehydration Percent when session loss is already known and you want body-weight context first, to Rehydration Plan when replacement timing is the next job, or to Calorie Planner, Protein Intake, or Macro Calculator for nutrition targets.

Add hydration before the nutrition plan gets too detailed
This page fills the daily hydration baseline between high-level calorie planning and meal-by-meal execution.
How to choose between nearby pages
Use Ideal Weight when the open question is the target body-weight range itself. Use Calorie Planner when maintenance calories or the direction are still open. Use Calorie Deficit or Calorie Surplus when the calorie gap is already known. Use this page when the missing baseline is hydration, not energy. Move next to Hydration Schedule once the daily liters are fixed and the remaining job is timing, to Sweat Rate when you have workout weigh-in data and need a session-specific fluid-loss estimate, to Dehydration Percent when that session loss is already known and you want relative body-weight context, and to Rehydration Plan once replacement timing is the next job. After hydration is clear, move to Protein Intake or Macro Calculator for daily nutrition, then to Meal Calorie Split, Protein Per Meal, or Macro Per Meal when execution by meal is the next job.
FAQ
What does this page calculate?
It estimates a simple daily water baseline from body weight, activity level, and climate, then converts the result into liters, milliliters, fluid ounces, and cups.
Is this medical hydration advice?
No. It is a planning shortcut only. If you have a medical condition, heat illness risk, kidney concerns, or fluid restrictions, use professional advice instead.
How is this different from calorie or macro pages?
Use this page for a hydration baseline. Use calorie, protein, and macro pages when you need energy or nutrient targets instead.
Does the share URL store anything except settings?
No. The share URL stores weight, unit, activity, and climate only.
