How to calculate fuel economy and usage
- Litres per 100km fuel economy calculator. Divide the litres it took to refill the tank by the distance travelled and multiply by 100.
- Kilometres per litre fuel economy calculator. Divide the kilometres travelled by the amount of litres it took to refill the tank.
- Keeping it accurate.
To calculate it, start by finding the kilometers per liter, then convert to liters per 100km. The fuel consumption in kilometers per liter is equal to the distance travelled divided by the petrol consumed. Now, find liters per 100km by dividing 100 by the km per liter.
Divide total miles by total gallons.
Use your trip odometer to see how many miles you traveled total, then divide this by gallons to get your average fuel consumption. While this is the exact number of miles per gallon during your test period, it is a good estimate for your car's average fuel consumption.The actual amount varies by vehicle and driving style and conditions. If you have liters/km but want the km/liter figure, just invert the liter/km figure, e.g. use the 1/x on your calculator, then multiply by 100. 8.2 km/liter becomes 12.19 l/100km and 12.3 km/liter becomes 8.13 l/100 km.
In more recent studies, the average fuel economy for new passenger car 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. The average fuel economy for new 2017 model year cars, light trucks and SUVs in the United States was 24.9 mpgUS (9.4 L/100 km).
How much fuel does a car burn in 1 km? Roughly (very roughly) between 0.05 and 0.20 litres per km, depending on so many things but mostly engine size.
Price per kilometre
You can take the cost for your fuel per tank and divide it by the kilometres driven to find out your fuel cost per kilometre.To estimate the fuel cost for a trip you must know the trip distance, the average per litre cost of fuel and the vehicle's fuel consumption.
- Divide the trip distance by 100.
- Multiply the result of this by the fuel consumption.
- Then multiply this figure by the cost of fuel/litre.
Petrol prices in India stood at Rs.71.75 per
litre at the start of the month of March.
Trend of Petrol Price in India for March 2020 (Rates per litre):
| Parameters | Rates/litre |
|---|
| 1st March | Rs.71.75 |
| 31st March | Rs.69.63 |
| Highest Rate in March | Rs.71.75 |
| Lowest Rate in March | Rs.69.63 |
The average of a set of numbers is simply the sum of the numbers divided by the total number of values in the set. For example, suppose we want the average of 24 , 55 , 17 , 87 and 100 . Simply find the sum of the numbers: 24 + 55 + 17 + 87 + 100 = 283 and divide by 5 to get 56.6 .
So one litre of diesel will give up about 3.3kWh (30% of the 10 kWh) – the remainder of the energy goes out of the exhaust pipe mainly as hot gas!
The actual formula to get km per litre is 100 divided by 8 = 12.5 (Your car will give you 12.5 km on one litre).
Diesel Generator Fuel Consumption Chart in Litres
| Generator Size | Approximate Diesel Fuel Consumption |
|---|
| ¼ Load (litres/hr) | Full Load (litres/hr) |
| 8kW / 10kVA | 0.8 | 2.4 |
| 10kW / 12kVA | .9 | 2.9 |
| 12kW / 15kVA | 1.1 | 3.6 |
On average, an in-tune four-stroke gasoline engine will burn about 0.50 pounds of fuel per hour for each unit of horsepower. Likewise, a well-maintained diesel engine burns about 0.4 pounds of fuel per hour for each unit of horsepower it produces.
3 to 6 km per liter. Can 1 litre of gasoline (out of a 50-litre tank) be added to an older model ('99 to '05) diesel car to aid in cold weather starting?
Today's Diesel Price in Indian Metro Cities & State Capitals
| City | Today Price | Yesterday's Price |
|---|
| Mumbai | ₹ 67.05 | ₹ 67.13 |
| Chennai | ₹ 67.57 | ₹ 67.65 |
| Gurgaon | ₹ 63.44 | ₹ 63.47 |
| Noida | ₹ 64.58 | ₹ 64.50 |
In general terms, 5-8 litres per 100km would be considered good fuel efficiency, 8-12 litres per 100km would be average, and more than 12 litres per 100km is considered fairly poor fuel efficiency. Your own driving habits have a big impact, too.
The minimum you get is 17 kms to the litre for a petrol in town and upto 28 kms to the litre for a diesel. On the highway.
Depends on the vehicle… me, being in an 80,000 pound semi truck, I can go about two miles give or take. In an average diesel car you will realistically get at least 50–70 miles per gallon. A gallon is about 4.5 litres so you should get about 12–14 miles.
Take that number and multiply it by the cost of gas per litre (currently about $1.30 to $1.40). That will give you the cost of driving 100km (usually somewhere between $10 and $20). If you want to know the figure for a single kilometre, that's easy, since you just divide by 100.
"You can get up to maybe 250,000 km or 300,000 km before a gas engine starts to make noise, or burn oil because it's wearing out, but a diesel can quite easily do 500,000 km and still be in excellent shape," says one certified mechanic I spoke with.
