SwitchExplanation
1 fluid ounce converts to 0.125 cups using one fixed beverage volume standard, so pours, service sizes, and storage labels stay comparable across the same unit system.
Fluid Ounces: a US customary liquid-volume unit used for pours, menus, and beverage labeling.
Cups: a US customary liquid-volume unit used for recipe-style beverage measurements.
This route is useful when converting between common beverage serving and container units while keeping the same fixed liquid-volume standard.
This conversion is purely multiplicative because both units stay inside one fixed beverage volume standard with no density assumption and no offset term.

Frequently Asked Questions
Are fluid ounces the same as ounces (weight)?
Fluid ounces (fl oz) measure volume while ounces (oz) measure weight, so this page stays inside the volumetric dimension.
Does this assume a US cup?
Yes. It uses the US customary cup defined as 236.588 mL so the result matches the site's shared cup definition.
Are decimals supported?
Yes. Decimal fluid ounce inputs apply the precise factor so the resulting cup totals remain accurate.
Why do recipes sometimes list fluid ounces instead of cups?
Fluid ounces can describe pours more precisely for bars and recipes, and this converter shows how those pours relate back to cups.
