How Much Petrol Will I Use Calculator?

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 can I figure out how much gas I’ve used?

  • Fill up your tank to the brim.
  • If your vehicle has a trip odometer, reset it or record the mileage on the master odometer.
  • Drive your car regularly and let your petrol tank get down to half a tank of gas.
  • Return to the petrol station and top off your tank.
  • Keep track of how much gas it took to fill the tank.
  • Make a note of the total distance traveled or the new odometer mileage.


  • Subtract the original odometer reading from the new one to get the miles traveled from the trip odometer.
  • Subtract the number of miles traveled from the number of gallons used to fill the tank. Your car’s average miles per gallon yield for that driving period will be the result.

Calculate how much fuel my engine consumes.

It’s crucial to remember that depending on how fast you’re traveling and other factors, your fuel consumption may reduce or increase. A gasoline meter put on your boat is the only true way to measure fuel use. However, while calculating your fuel use isn’t always perfect, it’s a wonderful place to start! On the sea, miles are difficult to measure, hence Gallons Per Hour (GPH) is utilized instead of the conventional MPH.

Pen and Paper Method

To use these formulas on your boat, “…plug in its horsepower rating, multiply it by the particular fuel consumption average, then divide the result by the fuel specific weight.”

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 much gasoline do I use every kilometer?

If you know the price of gasoline, simply multiply the price per litre by the result to get your cost per 100 kilometers. For example, if gas costs $2 per gallon, 8.98l/100km means it costs $17.96 to drive 100 kilometers, or $0.18 per kilometer, excluding other expenditures such as wear and tear.

What is the formula for calculating litres per kilometer?

If you know the distance traveled and the amount of fuel consumed to travel that distance, calculating your car’s fuel consumption is simple. This is what you must do:

  • Fill your tank with gasoline.
  • Make a note of the current miles on your odometer. Reset the trip odometer on your automobile if it has one.
  • Continue driving normally until you need to refuel.
  • Fill up the fuel tank when it’s empty.
  • Keep track of how much fuel you used.
  • Use your trip odometer to figure out how far you’ve driven since your last fill-up. If you don’t have a trip odometer, subtract the first odometer reading from the latest odometer reading to figure out how far you’ve gone.
  • Simply divide the total distance travelled by the total litres of fuel used to get how many kilometers your automobile can travel on one litre of fuel. For example, 400 kilometers divided by 42 litres equals 9.5 kilometers per litre.
  • To calculate the fuel efficiency of your car (Metric System), multiply the amount of fuel consumed by 100 and divide by the total number of kilometers driven. Example: 42 litres multiplied by 100 / 400 equals 10.5 litres every 100 kilometers.

Tip: To compare your fuel economy over time, repeat this step at random. If your fuel economy suddenly improves, it could be a sign of a mechanical problem that requires professional care. Many things might have a good or negative impact on your vehicle’s fuel economy. Driving styles, road conditions, and your car’s general mechanical condition are all elements to consider.

What is the fuel consumption of a 1500cc automobile per kilometer?

In Kenya, the Toyota Fielder is one of the greatest 1500cc automobiles. This vehicle is adaptable and will easily fulfill your personal and business demands. Its large cargo space makes it an excellent family vehicle. Roof rails, fog lights, alloy rims, and a spoiler are among the Fielder’s exterior features. Reverse sensors, retractable side mirrors, and side mirror indicators are standard on higher trims.

The Fielder’s interior is simple yet utilitarian, with enough of head and legroom in both the front and rear seats. For tall persons, though, the center back seat can feel a touch cramped. With a blend of luxury and comfort, this car is practical, reliable, and fuel-efficient. Fielder boasts one of Toyota’s most dependable engines, capable of running for kilometers without trouble.

The Toyota Fielder’s 1500cc 4-cylinder engine has an average fuel consumption rating of 18.0km/L. It takes 10.2 seconds to accelerate from 0 to 100 km/h.

How do you calculate the cost per kilometer?

Given the variable price of fuel in South Africa, the cost per kilometer of petrol and diesel vehicles is based on an ever-changing formula. There are also some pricing changes depending on where you reside, but coastal costs have historically been lower, so we’ll use them to compare against EVs for fairness.

At the time of this experiment, a litre of unleaded 95 petrol cost R20.88 at coastal prices, and a gallon of 50ppm diesel cost R18.96. Simply take your trip computer’s average fuel consumption in litres per 100km (l/100km), split it by 100, and multiply the result by the gasoline cost per litre to calculate your current car’s cost per kilometer.

Jaguar South Africa has put together an useful infographic to help you figure out how much your car costs in terms of gasoline per kilometer driven:
