To find the conversion factor between gallons and liters, we need to know the conversion factor between these two units.

1 gallon is equal to approximately 3.78541 liters.

Using this information, we can calculate the conversion factor as follows:

Conversion Factor = Number of liters / Number of gallons

Since a barrel of oil is exactly 42 gallons, the conversion factor can be found by multiplying the number of gallons by the conversion factor between gallons and liters:

Conversion Factor = 42 gallons * 3.78541 liters/gallon

Simplifying this calculation gives:

Conversion Factor = 159.00822 liters/barrel

Therefore, there are approximately 159.00822 liters of oil in a barrel.
