What is the conversion method for litres to gallons?

The correct method for converting litres to gallons involves aligning US gallons on the inner scale with litres on the outer scale of a conversion tool, such as a flight computer or a conversion chart. This technique allows for a straightforward reading of the equivalent volume in gallons for any given amount of litres.

When you align the scales correctly, you can easily determine how many gallons correspond to your specified litres, providing an efficient way to make this conversion without complex calculations or additional measures. This method is particularly useful for pilots and navigators who need to perform quick conversions while in flight or during planning.

Other methods mentioned, such as using weight or direct conversions, do not apply here as they introduce inaccuracies and aren't relevant for volume-to-volume conversions, which is what the question is focusing on.
