Of course if you wanted to be pedantic, you could argue that since we are talking about fuel consumption we should state it as how much fuel is consumed. So litres goes on the top of the fraction and the distance goes on the bottom. Putting the distance on the top of the fraction whether it is miles or kilometre surely means that whatever the figure describes it is not actually fuel consumption.
The 100 is not an issue. It is only there the give a reasonable degree of accuracy without too many decimal places. I know it involves the same number of significant figures, but 10.5Litres/100km looks neater than .105Litres/km. Anyway working with 10s or 100s is not a big deal. You don't really have to do any maths. Just move the decimal point up or down one or two places.

Not true. Canada and Europe use it. See also Keys Corner » Blog Archive » Where do people use “km/liter” for fuel consumption?

and from an EEC Directive:

Note the Directive is dated 1993.

john! whats are these fuel tank dipsticks you have? enlighten me, i could do with 1!

All Australian military Series 2a (and probably Series 3) Landrovers are fitted with a calibrated brass dipstick in each tank. These have a screwdown fitting soldered to the top of the tank, and a hole in the panel above them to access the dipstick and to allow the entry of dust.

For anyone with a lathe, copying these would be quite easy, but it would be best to find an ex-army Series to have a look at what is involved.

I suspect that, as in Australia, while officially it is l/100km, many if not most people use km/l, the same as many here use mpg, but with even more tendency to continue the old way because no change of units is involved.

Interestingly, I am currently reading a book ("Measure of all things", Ken Alder) on the establishment of the metre by measurement of an arc of the meridian in 1789-96. It gives details of the adoption of the metric system. In France, it was introduced in 1795 (with a provisional metre), abolished in 1806 in favour of traditional Paris measures (as part of Napoleon's rapprochement with the Catholic Church prior to his Russian adventure), and reintroduced after the 1830 revolution. But according to the author, it did not replace the traditional measures in everyday practice until after the Great War (1914-18), when the metric system, used by the military, was indoctrinated into everyone who either served in the army or dealt with it - which meant just about everyone in France! It had been adopted earlier (1820s onward) as part of the unification efforts in the Netherlands and later in Germany and Italy for the same reason (And spread to their colonies).

a couple of points
firstly what was the specific gravity of the fuel in the vehicle, the fuel poured in to the tank ,get the average , average temp multiply the refuel quantity by average specific gravity to give you the correct vol in lts or gals then start your calcus

forget that,, I want to know what kind of calculator Ladas has that goes to 31 places

Its a gas gas gas!

Most computer converters/calculators will go to the enth degree and not revert to E or r

I have three little progs/facilities that I use

Conversions in Hand - used for a PDA, but sits nicely on the PC - but doesnt work with Vista

World Time - from the famous watchmaker website (bloody handy tool) Brietling - not only does it offer world time in real time, but there is currency and engineering conversions

Then I also use Currency Converter RX which gives me up to the min exchange rates on certain currencies (well most of them) its online so very accurate

All of these go in excess of 31 places

Christ I really need a life don't I

The real problem lies with the 'imperial' system.

Mile - Nautical or Statute
Furlong/Chain/Yard/Foot

But then of course there was the imperial 'metric' measurements in land surveying where a chain was 100 links.

Not to mention acres, rods, roods and perches never did get the hang of them.

I grew up with imperial then changed to metric at the end of my schooling, what never ceases to amaze me is young guys (around 30) that would have been metric all their life yet, ask how tall they are and you get 5' 10", recently moved onto the 'land' measures rainfall in points and lives on acres - how does that happen ??

Perhaps that stems from two things,

1: Growing up they would have had their height measured by their parents, possibly using the imperial system.

2: Having to explain to old people who only 'understood' imperial measurements what their height in cm actually meant.
Incidentally, my Dad (an engineer of some repute) always used to drill mm into me, saying cm are for dress making .
