Step 2: Gallons to Liters

Next, we convert gallons to liters. There are approximately 3.78541 liters in a gallon. So, for 1 gallon:

  • 1 gallon * 3.78541 liters/gallon = 3.78541 liters

Calculating Fuel Efficiency

Now, we can calculate the fuel efficiency in liters per 100 kilometers. We'll use the total kilometers (35.4479 km) and the total liters (3.78541 liters) to find out how many liters are used to travel 100 kilometers:

First, we find out how many times 35.4479 km goes into 100 km:

  • 3.78541 liters * 2.8284 = 10.753 l/100km

Comparing Fuel Efficiency

Now that we have the fuel efficiency in l/100km, we can compare it with other vehicles. Here's a quick comparison:

Fuel Efficiency (l/100km) Equivalent MPG
10.753 22 mpg
6.0 40 mpg
4.5 52 mpg

As you can see, a fuel efficiency of 10.753 l/100km is quite good, equivalent to 22 mpg.

So, there you have it! Converting mpg to l/100km is a straightforward process once you understand the conversions involved. Happy calculating!
