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

“…put in its horsepower rating and multiply it by the specific fuel consumption average, then divide the product by the fuel specific weight,” says the author. *

## What is the formula for calculating diesel consumption?

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.

- Subtract the number of miles travelled from the litres of gasoline consumed (miles per litre)

### 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 do you figure out how much fuel you’ll need every hour?

Divide the amount of miles you went by the time it took you to arrive at your average pace. For example, if you went 200 miles in 4 hours, your average speed would be 50 miles per hour. To calculate how many gallons of fuel you’re burning every hour, multiply your average speed by the miles per gallon.

## What is the kWh value of a litre of diesel?

The energy content of one litre of diesel fuel (auto) is approximately 38 MJ, which is roughly 10 kWh (using a ballpark figure), however the conversion efficiency into kinetic energy is only about 30%, which is better than petrol, which is normally 25% depending on the design.

## How can you figure out how much fuel you use per kWh?

How Do You Calculate A Diesel Engine’s Fuel Consumption Per Hour? A formula for calculating the maximum engine fuel consumption in gallons per hour (GPH) multiplied by the fuel specific weight. GPH = 7.2 (0.4 x 300)/hp = 105/7.2 = 17.6 in the case of a 300-hp diesel engine.

## How do you calculate fuel consumption in kilometers per liter (km L)?

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:

- Make a note of the current miles on your odometer. Reset the trip odometer on your automobile if it has one.
- 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 rate?

Before going any further, it’s important to define the terms fuel efficiency and fuel consumption; these two phrases are frequently used interchangeably and erroneously, resulting in misunderstanding and inaccurate interpretations:

Fuel economy is a metric that expresses how far a vehicle can travel on a gallon of gas. It is measured in miles per gallon. This is a common metric in the United States that has been used for a long time by customers; it is also used by vehicle makers and regulators, mostly to communicate with the public. Fuel economy is a metric that measures the distance traveled per unit of fuel.

The inverse of fuel economy is fuel consumption. It is the amount of fuel used to travel a specific distance. It is measured in gallons per 100 miles in the United States, and in liters per 100 kilometers in Europe and other parts of the world. Fuel consumption is a basic engineering statistic that is directly related to the amount of fuel spent per 100 miles and can be used to calculate volumetric fuel savings. It is actually fuel usage that is the issue.

## In Excel, how do I compute mileage?

To compute the total, use the formula “=(cell containing mileage) (cell containing rate)”. If your total miles are in E4 and your rate is in K4, for example, entering “=E4 K4” gives you the product of total miles and rate.

## How do I compute in Excel?

- In a cell, type the equal sign (=). This informs Excel that you’re inputting a formula rather than just numbers.
- Enter the equation you’d like to solve. To add 5 and 7, for example, type =5+7.

Instead of immediately inputting numbers in your calculation formula, you can place them in distinct cells and then refer to those cells in your formula, for example, =A1+A2+A3.

The table below demonstrates how to do simple arithmetic calculations in Excel.

The following is an example of what the outcomes of the preceding Excel calculation formulae can look like:

Apart from that, you can use the concatenation operator (&) to merge values from two or more cells in a single cell, as shown below:

Logic operators such as “greater than” (>), “less than” (=), and “less than or equal to” () can also be used to compare cells.

## How can you figure out how many hours it takes to run a marathon?

How can you figure out how many hours an engine has been running?

- Write down the overall mileage from your trip meter and the total time from your stopwatch after a week has gone.
- To get your weekly average travel speed, divide the mileage by the hours.
