In terms of liters, how many liters are equivalent to 1 gallon?

  1. 2.5 L

  2. 3.0 L

  3. 3.8 L

  4. 4.2 L

The correct answer is: 3.8 L

The correct answer is based on the established conversion between gallons and liters. One gallon is equivalent to approximately 3.8 liters. This conversion factor is crucial for understanding volume measurements, especially in contexts where both metric and imperial units are used, such as in scientific applications, cooking measurements, and various industries. When measuring liquids, knowing this conversion helps in accurately transferring or comparing volumes across different measurement systems. Thus, using the conversion of 1 gallon to 3.8 liters is a practical and widely accepted standard in both everyday usage and technical settings.
