Cups to Oz

Welcome to cups to oz, our article about the volume conversion cups to ounces.

As a matter of fact, the conversion of cups to ounces (oz) is ambiguous because there are three different cups and five distinct types of ounces in current use.

And all five ounces mean fluid ounces, not to be confused with the units of mass known as international avoirdupois ounce or the troy ounce.

However, instead of writing cups to fluid ounces, the adjective fluid or liquid is often left out when it clear from the context that a volume conversion is meant.
