KmL - Fuel Consumption Calculator is a free Android app designed to help you calculate the fuel consumption of your vehicle and determine whether it's more economical to use gas or ethanol. Developed by Renato Callegari Burkle, this app is an excellent tool for anyone looking to save money on fuel costs.

The app is very simple to use. All you have to do is enter your initial odometer reading, the amount of fuel you've used, and your final odometer reading. The app will then calculate your approximate fuel consumption per kilometer. Additionally, you can calculate the fuel consumption by entering the distance you've traveled and the amount of fuel you've used.

KmL also allows you to calculate the cost of your trip and determine whether it's more economical to use gas or ethanol. You can also calculate how many liters of fuel you can buy with a given amount of money, as well as how far you can go with that amount of fuel. The app also includes a feature that lets you calculate fuel consumption using compressed natural gas (CNG) in cubic meters, making it ideal for taxi drivers and ride-sharing drivers who use CNG.
