What is the simplest formula for calculating fuel consumption?
3 Answers
The relatively simple formula for calculating fuel consumption is: fuel consumption per 100 kilometers equals the volume of fuel consumed (in liters) divided by the distance the car can travel on that amount of fuel (in kilometers) multiplied by 100. For example, if a car consumes 4 liters of fuel to travel 50 kilometers, its fuel consumption per 100 kilometers would be calculated as 8 liters, commonly referred to as "8 liters per 100 km". Factors affecting fuel consumption: The fuel consumption per 100 kilometers of a car is not fixed. Different road conditions, load capacity, temperature, and whether the air conditioning is on all affect fuel consumption. Things to note: When refueling in urban areas, it is not advisable to fill the tank completely because city driving often involves frequent stops and starts. A full tank can increase the engine's load, resulting in weaker acceleration and higher fuel consumption.
I've been driving for over 20 years, and the simplest way to calculate fuel consumption is kilometers divided by fuel amount. The basic method is to fill up until the pump clicks off and note the odometer reading, then drive a few hundred kilometers and refill to full while recording the new fuel amount. The distance difference divided by fuel amount gives per-kilometer consumption, multiplied by 100 converts to the standard L/100km unit. For example, driving 400km using 38 liters gives ~9.5L/100km. Many factors affect this - steady highway driving saves fuel while city traffic increases consumption. Underinflated tires create more resistance, and regular maintenance helps reduce fuel use. Recording multiple trips and averaging makes calculations more accurate and practical.
I just started learning to drive, and the simplest formula for fuel consumption is to divide the distance traveled by the amount of fuel consumed. Fill up the tank, drive for a while, then go to the gas station to fill up again and note the amount of fuel added. Divide the difference in kilometers by the liters of fuel added to calculate the fuel consumption per 100 kilometers. Mobile apps like Fuel Consumption Manager can automatically calculate this for you by entering these numbers, which is quite convenient. On the highway, maintaining a steady speed is better than sudden acceleration, and using the air conditioning less can also save some fuel. Remember to try it several times to avoid errors.
