The real method for calculating km per litre is 100 divided by 8 = 12.5, which means that one litre of gas will bring you 12.5 kilometers.
How do you figure out how many kilometers per litre?
Simply divide 100 by the number of liters next to the “L” to get kilometers per liter. If the reading is 6L/100km, divide 100 by 6, and you’ll get 16.6 kilometers per liter (km/L).
What is the average number of kilometers per litre?
While petroleum engines’ thermal efficiency (mechanical output to chemical energy in fuel) has improved since the dawn of the automobile era, it is not the only factor affecting fuel economy. The fuel economy is influenced by the overall design of the vehicle as well as its usage pattern. Because of differences in testing methodologies, published fuel economy varies by jurisdiction.
The Mobil Economy Run, which took place every year from 1936 through 1968 (excluding during World War II), was one of the earliest studies to measure fuel economy in the United States. It was built to deliver accurate fuel economy figures during a coast-to-coast test on real highways, with typical traffic and weather circumstances. The run was sponsored by Mobil Oil Corporation, and it was sanctioned and controlled by the United States Auto Club (USAC). The average fuel efficiency for new passenger cars in the United States improved from 17 mpg (13.8 L/100 km) in 1978 to more than 22 mpg (10.7 L/100 km) in 1982, according to more recent research. In the United States, the average fuel economy for new 2020 model year cars, light trucks, and SUVs was 25.4 miles per gallon (9.3 L/100 km). The US EPA classified 2019 model year cars (including EVs) as “midsize,” with fuel economy ranging from 12 to 56 mpgUS (20 to 4.2 L/100 km). However, in response to environmental concerns raised by CO2 emissions, new EU regulations are being implemented that will reduce average CO2 emissions of cars sold beginning in 2012 to 130 g/km, or 4.5 L/100 km (52 mpgUS, 63 mpgimp) for a diesel-fueled car and 5.0 L/100 km (47 mpgUS, 56 mpgimp) for a gasoline (petrol)-fueled car.
The average fleet consumption is not immediately affected by new vehicle fuel economy: for example, in 2004, Australia’s car fleet average was 11.5 L/100 km (20.5 mpgUS), compared to 9.3 L/100 km for new cars in the same year (25.3 mpgUS)
What does it cost to drive 100 kilometers?
But, in general, you should look for the type of car you have and then calculate how many litres of fuel it takes to run it. This is measured in litres per 100 kilometers (L/100km), with separate figures for city and motorway driving.
Many long journeys will include a mix of city and highway driving. To be conservative, I’d go with the city figure.
Multiply that figure by the cost of gas per litre (now around $1.30 to $1.40). This will offer you the price of driving 100 kilometers (typically between $10 and $20). It’s simple to calculate the figure for a single kilometer by simply dividing by 100. So, if driving 100 kilometers costs $11, driving one kilometer costs 11 cents.
In city driving, the Mazda5 consumes 9.9 liters per 100 kilometers. So, at $1.30 a litre, here’s the math:
How can you figure out how far a gallon of gasoline will go you?
If you’re using mpg (miles per gallon), the calculation for figuring out how much gas you’ll need is:
If the distance is 500 miles and the consumption rate is 20 miles per gallon, the total amount of fuel required is 500 / 20 = 25 gallons.
If you’re measuring consumption in gallons per 100 miles, the formula for determining the amount of fuel required is:
If the trip is 300 miles and the consumption rate is 5 gallons per 100 miles, you will require 300 / 100 x 5 = 15 gallons of gas.
Both methods work for metric quantities, such as kilometers and liters; just make sure you don’t mix them up. You may avoid making that mistake by using an online fuel calculator.
How do you figure out how much fuel you’ll need?
You won’t be able to tell if your new driving style and skills are effective unless you know your car’s average miles per gallon (mpg). On-board computers are available in some vehicles, however they are not always reliable.
When you fill up your automobile, fill it all the way up and make a note of:
- Your mileage since the last fill
- The amount of fuel you put in litres
- The price of a litre of gasoline
Then simply enter your information into the fuel consumption calculator below:
Alternatively, you may figure it out for yourself:
- Fill your tank all the way to the top.
- The trip counter is reset to zero.
- Make a note of how far you’ve drove the next time you fuel up.
- Fill the tank up again, and keep track of how many litres you put in.
- Subtract the number of miles travelled from the litres of gasoline consumed (miles per litre)
- Multiply the value by 4.544 to get miles per gallon.
Example
Stages one and two are completed by Frank. When he next fills up, his trip meter reads 160.1 miles. Filling his tank takes 22.3 litres. Frank calculates his gasoline consumption to be:
How much gasoline does a 2 liter engine consume?
To drive a mixture of air and fuel into the combustion chamber, each piston rises up inside its cylinder. It’s compressed and burned here, and the explosive force drives each piston to return to its cylinder. It is this momentum that is used to generate engine power. When a four-cylinder engine is referred to as a 2.0-litre engine, it signifies that each piston can compress around 500cc of fuel and air into the combustion chamber for each revolution of the engine.
If the engine is spinning at 3,000 rpm, each piston in the engine can burn 500cc of gasoline and air 3,000 times per minute. An engine’s power is usually proportional to how much air and fuel it can burn.
How does engine size affect performance?
Because a larger engine can burn more fuel and produce more power, a car with a larger, more powerful engine can normally accelerate quicker and haul heavier loads than a car with a smaller engine.
This rule of thumb is no longer as accurate as it formerly was. Because of advancements in engine technology, some of today’s smaller engines can create more power than certain older, larger engines. Turbocharging, which pumps more air and fuel into each cylinder, is one key to this.
How does engine size affect fuel economy?
Because a larger engine can burn more fuel per revolution per minute (rpm), it will typically spend more fuel during the same journey than a smaller engine.
How can I calculate the cost of gasoline per kilometer?
Let’s say your trip computer (or the manufacturer’s website) states your automobile consumes 8.0 litres of gasoline every 100 kilometers. The real method for calculating km per litre is 100 divided by 8 = 12.5, which means that one litre of gas will bring you 12.5 kilometers.
Is 10 kilometers per litre a good number?
Anything with a fuel consumption rating of less than 6-litres/100km or more than 16.5km/1-litre is deemed good. litres per 100km (litres/100km) is the first (and most popular) reference. This is the amount of fuel required for an automobile to travel 100 kilometers.
