Rough daily water estimate
1800～2100mL/day
This is a rough adult reference, not a target you must reach. Food and other drinks contain water too; do not drink a large amount at once.
In your cup, approximately7.2～8.4 cups/day
Worked steps
- 60 × 30～35 = 1800～2100 mL
- 1800～2100 ÷ 250 = 7.2～8.4
Taipei health authorities describe 30–35 mL per kilogram as a general adult estimate, not a personal prescription or mandatory target. If you have an illness or fluid restriction, are pregnant or breastfeeding, or are under 18, ask a medical professional instead. Food and other drinks contain water; activity, weather and health affect needs. Drink gradually, not a large amount at once. The HPA's general 6–8 cups (240 mL each) is a separate reference.
Method and scope
A rough adult reference from Taipei health authorities uses 30–35 mL per kilogram per day. It is not a personal prescription or a mandatory target.
If you have an illness, have been told to restrict fluids, are pregnant or breastfeeding, or are under 18, ask a medical professional instead of using this estimate. Food and other drinks contain water; activity, weather and health affect your needs. Drink gradually, not a large amount at once.

What this tool does
Estimate a general adult daily drinking range from body weight; this is not a personal medical target.
What to enter
Enter body weight in kilograms and your cup or bottle capacity in millilitres.
Worked example
For 60 kg and a 250 mL cup, the formula gives 1,800–2,100 mL, or about 7.2–8.4 cups.
How it is calculated
Multiply kilograms by 30 and 35 for the two endpoints, then divide each by cup capacity.
Understanding the estimate
The result is a rough reference, not an instruction to force yourself to drink. Food and other drinks also contain water.
Limitations
Ask a medical professional if you have a condition, fluid restriction, pregnancy, breastfeeding, or are under 18. Needs vary with activity and weather; avoid drinking a large amount at once.
