What This Calculator Does
Calculate coffee-to-water ratio by brew method.
It combines Brew Method, Water Amount, Coffee Amount, Number of Cups to estimate Coffee Needed, Water Needed, Ratio.
Formula & Method
Given brew ratio 1:r, coffee-water relation is Water_{mL}=Coffee_g\cdot r and Coffee_g=\frac{Water_{mL}}{r}. Fluid ounces use fl\,oz=\frac{mL}{29.5735}.
Notation used in the formulas: R = Coffee Needed; x_{1} = Brew Method; x_{2} = Water Amount; x_{3} = Coffee Amount; x_{4} = Number of Cups.
Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.
Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
