How many ounces are in 1 US Gallon?

A US gallon is equivalent to 128 fluid ounces. This conversion is fundamental in understanding measurements, especially in fields like pest control where precise dosing of liquids is often required. Knowing that there are 128 ounces in a gallon can help when diluting pesticides or other chemicals, ensuring that applicators mix solutions correctly for safe and effective use.

The other options, while they represent quantities, do not reflect the correct conversion from gallons to ounces in the US measurement system. For example, the option suggesting 64 ounces reflects the volume of half a gallon, and 16 ounces is the volume of a quart, which is a quarter of a gallon. The incorrect option suggesting 512 ounces is actually double the correct amount. Understanding these conversions is crucial for anyone involved in field applications where accurate measurement is essential for compliance with safety regulations and effective pest management.
