To compare the efficiency of the two vehicles, we need to convert them to the same unit. The car getting 31 miles per gallon offers about 13.2 kilometers per liter, which is calculated by converting miles to kilometers (1 mile = 1.60934 km) and gallons to liters (1 gallon = 3.78541 liters). Thus, the car with 31 miles per gallon is more efficient than the one achieving 12 kilometers per liter.
When evaluating fuel efficiency, it’s often helpful to know that higher numbers indicate better performance. You can use online calculators to convert between different units of fuel efficiency, which can simplify comparisons. Avoid common mistakes, like forgetting that a higher MPG (miles per gallon) translates to a more economical choice!
