Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- No per-prompt or provider footprint claim. Match consumption versus withdrawal boundaries and avoid overlap between factors. Scenario calculation using your supplied factors. Defaults are illustrative inputs, not verified regional or product-specific measurements.
Example Calculation
- IT electricity used: 10 kWh
- Facility power usage effectiveness: 1.2
- On-site water per IT kWh: 0.5 L/IT kWh
- Electricity water intensity: 1 L/facility kWh
10 IT kWh, PUE 1.2, on-site WUE 0.5 and electricity intensity 1 give 5+12=17 L.
Frequently asked questions
How do I use this calculator?
Enter it electricity used, facility power usage effectiveness, on-site water per it kwh, electricity water intensity. The result updates automatically. Use Reset to restore the example values.
What method does it use?
on-site water=IT kWh × WUE; electricity-linked water=IT kWh × PUE × grid water intensity.. No per-prompt or provider footprint claim. Match consumption versus withdrawal boundaries and avoid overlap between factors. Scenario calculation using your supplied factors. Defaults are illustrative inputs, not verified regional or product-specific measurements.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
