Interesting numbers
1.8 L × 365 ≈ 657 liters of drinking water per year.
This metric counts drinking water only. Household and agricultural water footprint is on a separate card.
In hot climates real need can exceed this average.
What this metric tells you
Drinking water is one of the most repeated lines in health advice. Ever Since Birth takes the middle of the 1.5-2 liter range, 1.8 liters per day, and applies it from your birth date to today. Tea, coffee, and soup are not split out in this simple model. The goal is not to be a hydration coach, but to show accumulated drinking water in liters.
In ten years you get roughly 6,570 liters, in thirty years about 19,700 liters. That allows bathtub and small tanker comparisons. Comparisons are curiosity, not a water-utility report.
In v1 national and global rows both carry 1.8. Real need shifts with climate, and that is deliberately deferred. Total water (household use, food production, indirect water) is a separate metric: totalWater. Do not mix it with drinking water.
Confidence is medium. The card has no estimated badge. The mini calculator shows one value. Large numbers use thousand separators for the English locale.

Deep dive
1.8 liters sits near the middle of common “drink enough water” advice. Tea, coffee, and water in meals are not split out in this simple model.
Total household water (showers, taps, laundry) is a separate metric; this card is what you drink from the glass. Seeing both on the home page makes the difference clear.
How does the water you drink become liters?
For directly consumed water, 1.8 L/day is the reference. Weight, climate, and habit surveys adjust this baseline with multipliers.

Core formula
result = seconds lived × (daily rate ÷ 86,400)
86,400 is seconds in one day. The daily rate is divided by that to get a per-second pace; multiplied by seconds since birth it yields total accumulation.
Step by step
01
Set up the second counter
Elapsed time from UTC birth date to the calculation moment.
02
Apply the 1.8 L/day reference
The daily liter rate is divided by seconds to assume a continuous “drinking speed.”
03
Add personal multipliers
Hot climate, weight, or factors like alcohol and smoking roughly change daily liters.

What it means
Lifetime water consumed is the silent accumulation of small glasses — a huge volume passed without always feeling thirsty.
Assumption for this comparison
Water tanker
Tipik su tankeri 5.000–20.000 L; 10.000 L orta nokta olarak seçildi.
This row is an estimated average. The range is in the source note.
