About Converting Fluid ounces to Cubic yards
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. Fluid ounce is typically associated with united States (beverage, nutrition labeling), while Cubic yard is typically associated with united States (construction material estimating).
Formula
cubic yards = fluid ounces × 0.0000386807163066
This factor comes from each unit's defined relationship to the category's base unit: 1 fluid ounce equals 0.0000295735295625 base units, and 1 cubic yard equals 0.764554857984 base units, so dividing one by the other gives the direct fluid ounce-to-cubic yard factor of 0.0000386807163066.
Simple example
1 fl oz × 0.00003868071631 = 0.0000386807 yd3
1 fluid ounce = 0.0000386807 cubic yards.
Real-world example
10 fl oz × 0.00003868071631 = 0.0003868072 yd3
10 fluid ounces = 0.0003868072 cubic yards.
