The US system still uses the measurement of Queen Anne’s gallon of wine, which was 3.785 liters, as their standard liquid measurement. Nowadays, America still uses the old British imperial measurement system as part of its own system of US customary units.

**Are US fluid ounces and dry ounces the same?**

No, US fluid ounces and dry ounces are not the same. US fluid ounces are a unit of liquid measurement, while dry ounces are used for measuring weights.

**What is the difference between fluid ounces and dry ounces?**

The difference is that fluid ounces measure liquids while dry ounces are used to weigh solid substances. For example, a fluid ounce would be used for a liquid measurement such as water, while a dry ounce would be used for a solid such as flour.

Typical measuring devices for fluid ounces are glass Pyrex volumetric measuring cups, while dry ounces are measured with plastic measuring cups and spoons.

**How many dry ounces in a gallon?**

A commonly used answer is that there are 110 dry ounces in one fluid gallon.

This conversion is based on an average density and must be adjusted for the solid substance you are trying to convert into a liquid measurement.
