Formula and methodology
Formula: Total water demand = people×litres per person per day×days.
The calculator turns a local planning assumption into a transparent total and reports cubic metres as a second unit.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- People — minimum 0; maximum 1000000
- Water per person per day — L/person/day; minimum 0; maximum 1000000
- Number of days — days; minimum 0; maximum 1000000
Worked example
| Input | Value |
|---|---|
| People | 4 |
| Water per person per day | 100 |
| Number of days | 7 |
Demand = 2,800 L, or 2.8 m³.
Assumptions and limits
- All inputs are nonnegative and daily use is constant across the period.
- The per-person amount is a visitor-entered planning rate, not a universal standard.
- Climate, sanitation, irrigation, price, availability, and conservation policy are not modeled.
