When travelling, each time I refuel, I fill the tank to the top, then read the trip meter & reset it to zero. I also note the reading on the cumulative speedo reading as a check.
The calculation for Litres per 100 km (that's the standard measure and the one that I always use) is -
Litres to fill multiplied by 100 (Read it off the bowser to two decimal places & remove the decimal)
20.24 L to fill becomes 2024
Divide this by the KM travelled
If we travelled 100 km since the last top up, then that is 2024 divided by 100 = 20.24L/100Km
summary
(Litres used x 100)/km
I have a small solar powered calculator in the folder with my fuel usage record book.
I have always kept a fuel usage record for all my long distance trips. The details are loaded into a spreadsheet on the laptop in the evenings, that has the following headings ...
Those headings with * are worked out by a formulae in the spreadsheet.
Comments include .. Strong Head wind, Following wind, Bumpy road, Freeway driving, Up/down mountain range, no towing, speeding, etc. that give a hint to why there may be a variation to the consumption.
I find that keeping an eye on the fuel usage gives a good indicator to how the vehicle is traveling. Also good for budgeting purposes. But I like doing this stuff so its good for the inner me too.
Most importantly, welcome to the forum Wandmill

There will be some one out there may have a formula but I use this , Drive 100 KLM use 10 litres of fuel , would mean you get 10 klm per 1 Litre

Gidday wandwill, this link may assist you, just take note of Klms when you fill up, then when you refill put in Klms travelled, and Litres put in, and it will convert it for you Automatically, http://motormouth.com.au/myvehicle/consumptioncalculator.aspx

I couldn't work mine out either so I filled the tank, drove 300 ks and refilled. It took 39 litres so I calculate 13 litres to 100 ks.

Thanks for that link dazren. That makes it so easy.
Sorry forgot, Welcome wandwill, you will get so much info on here.

Gday...
Cupie's got it one. Good and accurate system. I also record my odometre reading, record and then zero my trip meter and record the litres taken at east fill. I then transfer that to my spreadsheet to calculate my fuel usage and a host of other useful - and useless but interesting - information.
I also carry a paper ready-reckoner in the car to have a quick "reference check" at time of fill - eases an old inquisitive mind
Attached is a pic of the sheet - feel free to copy/print/use to your heart's content (or ignore)
Using the sheet - eg 60litres filled, covered 500km = 12.0ltr/100km.
Gee thanks Doug, You have very good taste in friends, EXCEPT, you also call wombat a friend ???? and with what he writes about you i cannot understand why ??/

Fill er up, set the trip meter to 0 and when i fill up again (Must fill it right up) I just pull out the calculator and divide the K's travelled by the fuel purchased. e.g. 1500 ks travelled. Purchased 150 litres 1500 divided by 150 = 10 litres per 100.
http://www.calculatenow.biz/conversions/consumption.php?fu=150&vol=lt&dt=1500&dist=km&fc=&ratio=lpk&submit=Convert#converter This is a good converter from the 150 litres to 1500 k's you get the following conversions

Here is my version. After each refuel: Divide the number of litres filled by the number kilometres travelled and mulitiply the result by 100 = litres per 100 km.
