Ever wondered how to convert miles per gallon (mpg) to liters per 100 kilometers (l/100km), the standard fuel efficiency measure in many countries? You're in the right place. We're going to demystify this conversion, using the example of 22 miles per gallon.

Understanding the Conversion

To convert mpg to l/100km, we'll need to perform a series of calculations involving miles, gallons, liters, and kilometers. Don't worry, it's not as daunting as it sounds. Let's break it down.
Step 1: Miles to Kilometers

First, we need to convert miles to kilometers. We know that 1 mile is approximately 1.60934 kilometers. So, for 22 miles:
- 22 miles * 1.60934 km/mile = 35.4479 km

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:

- 100 km / 35.4479 km = 2.8284
Then, we multiply this by the total liters to find the liters per 100 kilometers:




















- 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!
