As a consequence when the Imperial gallon goes beyond 20% in the gallon size then it becomes lesser by 4% in terms of the size of fluid ounce. When we talk about 1 avoirdupois ounce of water at a temperature of 16.67 degrees Celsius or 62 degrees Fahrenheit then it has exactly the same volume as of the Imperial fluid ounce. This appropriate conversion of fluid ounce to avoirdupois ounce system is not found in the US system of measurements.
