Formula and methodology
Formula: Water-to-coffee ratio = water mass/coffee mass; coffee percentage = coffee/(coffee + water) × 100.
The ratio uses coffee as the one-part reference, while the percentage describes coffee’s share of the two entered masses.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Coffee mass — mass units; minimum 1.0E-6; maximum 1000000
- Water mass — mass units; minimum 0; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Coffee mass | 20 |
| Water mass | 320 |
Ratio = 16:1; coffee share ≈ 5.882%.
Assumptions and limits
- Coffee and water masses use the same unit.
- Coffee mass is positive.
- Extraction, beverage retention, grind, temperature, and taste are not modeled.
