Which of the following is NOT a unit of liquid volume in the US?

In the context of measuring liquid volume, quarts, gallons, and pints are all standardized units used in the United States to quantify liquid quantities. These units are designed to provide a clear and consistent way to measure and compare liquid volumes for various applications ranging from cooking to scientific measurements.

In contrast, inches are a measure of length, not volume. As such, they cannot provide a meaningful representation of liquid capacity. Thus, when identifying which option is not a unit of liquid volume in the US, inches stands out as the only choice that does not fit within the category of liquid measurement.
