Classic tool
Simple Daily Water Estimate
Estimate a daily water target based on weight, activity and heat.
Use this tool as a simple daily hydration estimate, not as individualized medical advice. The target considers body weight, activity level and heat to provide an approximate daily intake.
It is useful as a starting point for routine, light training and personal organization, but real needs may change with health conditions, medication, pregnancy, fever, vomiting, diarrhea or professional guidance. Some daily water also comes from food.
Use clear inputs to get a more useful result.
How to use Simple Daily Water Estimate
Open the tool, fill in the fields with the data you already have and generate the result step by step. If you want to compare scenarios, change one field at a time so it is easier to understand the impact of each value.

Is the result ready to use without checking it?
It is better to treat it as support. Review the output once more before using it in a quote, document, spreadsheet, technical task or published page.
