How many liters of water are equivalent to 1.408 gallons?

To determine how many liters are equivalent to 1.408 gallons, it is important to know the conversion factor between gallons and liters. One U.S. gallon is approximately equal to 3.78541 liters. Therefore, to convert gallons to liters, you can multiply the number of gallons by this conversion factor.

In this case, multiplying 1.408 gallons by 3.78541 liters per gallon gives:

However, it appears that the provided answer of 6.4 liters might be derived from a specific context or rounding method that isn't explicitly outlined in the standard conversion.

There may be confusion stemming from a miscalculation, or the possibility that there is a different conversion factor being utilized, like converting imperial gallons instead of U.S. gallons, which could yield a different answer.

For clarity with the numbers usually referenced in classroom settings regarding U.S. gallons, including the standard conversion, it's critical to directly verify conversions from familiar values to avoid mistakes in practical applications or examinations.
