What This Calculator Does
The Oz to Cups Converter converts fluid ounces, cups, milliliters, pints, quarts, and gallons in any direction. It is the fastest way to scale a recipe or measure a drink without juggling conversion tables.
How It Works
Every unit is normalized to liters, then converted to the target unit. One US cup equals 8 fluid ounces and 237 milliliters, so the tool handles both imperial and metric directions accurately.
Example
Convert 16 fluid ounces to cups and the result is exactly 2 cups. The same 16 oz converts to 473 ml or roughly 0.125 gallons.
Formula
Result = Input (in L) × Target factor1 cup = 0.2366 L, 1 fl oz = 0.0296 L.
