Which term describes the volume unit whose value equals 3.785 liters per gallon?

• A. Gallon
• B. Meter
• C. Cup
• D. Liter

Answer: (D)

Understanding this involves the relationship between gallons and liters. In US customary units, one gallon equals 3.785 liters. So the volume unit that has that value is the gallon—the statement 3.785 liters per gallon is just another way of saying 1 gallon = 3.785 liters. The liter is the metric unit being used to express the same volume, but it does not define the unit that equals 3.785 liters for one gallon. The cup or meter aren’t involved in this specific conversion.
