Sixteen to One

Sixteen to One is a coffee-to-water ratio calculator. Enter your coffee or water amount, pick your brew method, and get an accurate ratio instantly — in grams, milliliters, cups, fluid ounces, or tablespoons.

No account. No ads. No subscription. No data collection. Just coffee math.

HOW IT WORKS

Pick a brew method — pour-over, French press, espresso, cold brew, drip, or AeroPress — and each one loads with its standard ratio. Type in how much coffee you have (or how much water you want), and the app calculates the rest. Adjust the ratio with a slider if you like it stronger or lighter.

FEATURES

• Works in grams, ml, cups, fluid ounces, and tablespoons — use whatever you're comfortable with

• Save favorites — store your go-to recipes for one-tap access
