How many fl oz in a ft?

Answer 1

This question cannot be answered sensibly. A fluid ounce is a measure of volume, with dimensions [L3]. A foot is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.

Answer 2

Quarts and fluid ounces are units of capacity. A foot is a unit of volume. The two units are therefore incompatible.

Answer 3

There are no fluid ounces in a foot. Fluid ounces are units of volume, while feet are units of length. The two measurements are not directly convertible into one another.
