About Converting Imperial fluid ounces to Cubic yards
Imperial fluid ounce and Cubic yard appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Imperial fluid ounce is typically associated with united Kingdom (historically; less common in current UK retail than metric units), while Cubic yard is typically associated with united States (construction material estimating).
Formula
cubic yards = imperial fluid ounces × 0.0000371628826935
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial fluid ounce equals 0.0000284130625 base units, and 1 cubic yard equals 0.764554857984 base units, so dividing one by the other gives the direct imperial fluid ounce-to-cubic yard factor of 0.0000371628826935.
Simple example
1 imp fl oz × 0.00003716288269 = 0.0000371629 yd3
1 imperial fluid ounce = 0.0000371629 cubic yards.
Real-world example
10 imp fl oz × 0.00003716288269 = 0.0003716288 yd3
10 imperial fluid ounces = 0.0003716288 cubic yards.

Understanding the Imperial fluid ounce
Imperial fluid ounce (imp fl oz) measures volume. The imperial fluid ounce is 1/160 of an imperial gallon: exactly 28.4130625 milliliters — slightly smaller than the US fluid ounce despite the larger imperial gallon, because it divides that gallon into more parts. It is classified as a UK/imperial customary unit.
Where it's used: United Kingdom (historically; less common in current UK retail than metric units)
Imperial fluid ounce vs. US fluid ounce. Confusingly, the imperial fluid ounce (28.41 mL) is slightly smaller than the US fluid ounce (29.57 mL), even though the imperial gallon is larger overall — because the imperial gallon is divided into 160 fluid ounces rather than the US gallon's 128.
