Converter Calculator
1 Cups = 8 Fluid Ounces
Explanation
The US cup (236.588 mL) divided by the US fluid ounce (29.5735 mL) equals 8 US fluid ounces, so this calculator keeps every cup-to-fluid-ounce step aligned inside the customary system. That preserves the inherent volume relationship while staying inside familiar pouring units.
It helps mix cup-based recipes with beverage pours while decimal cups and ounces stay precise because the same fixed volume definitions are applied. It also ensures beverage volumes stay tied to the customary definitions for consistent pouring guidance.
