MPG Calc

Mark Fill the tank to the brim,travel till allmost empty then fill it again to the brim. x amount of litres divide the litres by 4.55 will give you galls then divide the no of gallons into the total milage,
ex 85 ltrs divide by 4.55 = 18.68 galls total milage was 545,so 545 divide by 18.68 = 29.17 mpg
thats how I do it anyway,
no doubt some others on the forum will say different Glenn.

I presume that arithmetic isn't your strongest subject.
Miles covered multiplied by 4.545 divided by litres used.
What will the answer mean to you?

Here is an additional thought, the speedometer in most cars is slightly optimistic, typically I find that of four vehicles I regularly use they are about 3mph fast checked against a GPS with speed indication thus and indicated 60mph is more accurately only 57. or about 2%
Given that error it is likely that the mileometer will have a similar in accuracy, thus if you calculate an mpg of 30, will only be 29!

Although speedometers are, on the whole, slightly optimistic, odometers aren't. The error in distance recorded could go either way, regardless of the accuracy of the speedometer.
My GPS agrees with the car 100%.
Isn't it irritating that manufacturers still use MPG instaed if MPL, I guess until we convert to kilometres there will be no change.

most modern cars work it all out for you with the on board computer they normaly give MPG , MPL, average speed ,miles until your next fill up ,outside temperature
Strictly speaking, miles per gallon is not a measure of fuel consumption at all, but of specific fuel consumption. As the car doesn't consume miles but gallons (or litres) of fuel, the unit used should come first and consumption should rightfully be measured in gallons (or litres) per mile. Convention has it the other way, but it's not correct.
You are correct of course Lutz but the convention evolved out of people wanting to know how far (in miles) would a gallon get them in their car - hence miles per gallon.
As Rioja's request for MPL - At least MPG sticks to Imperial measurements! - Having just spent time with an Aussie who thinks in Kilometres/Litre - this seems a better option to me as it gave a more "user friendly" range.
But do we want to give up "our miles"?

Miles per litre as an official measure of fuel consumption would be a bastard set of units, half metric, half Imperial, and would certainly put the UK out on a limb with something not directly comparable to anywhere else. Even miles per gallon is something of an anomaly now. Only the US still uses them, too, and their gallons are different anyway. Elsewhere, litres per 100km seem to have gained overall acceptance although, so long as miles are still the norm in the UK, it makes calculations a bit awkward. The only other country in the world that I know of that has another quirk of a unit is Japan. They measure in kilometers per litre, another incorrect defintion of fuel consumption. Until a couple of years ago, petrol was sold in the Gulf States in Imperial gallons but distances measured in kilometres, so they had the opposite situation to the UK (however, they've changed to litres now except in some out-of-the-way petrol stations with old pumps).
It's ironic that we have a Goverment that will procecute if you sell oranges in Lbs, but have not yet started a programe of converting miles to kilometres. Ok so it would be difficult to convert all the signs overnight, but could it not be done county by county over say 60 days. Lets face it most people would understand that the limit has not been raised overnight even though on the motorway it should be raised to say 130 klicks.

What is the offical definition of a Klick? is it Kilolitres in centikilometers?
Like many of us I started school when the systems of measuerments was Feet Lbs + Seconds, It then changed to Centimeter Grams seconds, then to Kilograms, Meter and seconds, which is basically the SI sytem which followed. Now we have Klicks!
Somehow I suspect that soon we will be using mpH (milimeters per hogshead) gpl (gills per lightyear)

John,
"Klicks" or even just "K" is a radio spoken short-hand for kilometres - it was certainly common when I started flying in the mid 70's - and I guess it's ex-military.
And in the metric system, the basic units have always been the metre, second and gram - the addition of the prefix modifier (kilo - 1000, centi - 100, milli - 1/1000, micro - 1/1000000) are just there to make the scale more "accessible"

Val and Frank changing the signs would be fairly easy if phased in as it was proposed to do in Ireland to switch to driving on the right it was proposed to phase it in over a few weeks!
You pulling my plonker ?? Even the Irish from Tralee would know it would take more than a Year to change to driving on the right
Val & Frank
At some point in the near future, any remaining imperial measures will be banned, we shall have to drive on the right, all distances will be in kilometers and speed limits will be unified across the whole of the EU.
The bureaucrats of Europe are determined to enforce uniformity on all of us.
Don't shoot the messenger, I wouldn't vote for any political party that included all this in their manifesto but others like me usually get dismissed as "grumpy old people".

Agreed! - but remember that only in the UK will such directives be rigorously enforced! - Most of the rest of the EU (France in particular, closely followed by Spain and Italy) will just ignore any such nonsense if it does not suit them and carry on doing what they have always done. And I am certainly NOT knocking those countries for doing so.
Whereas our officials will enforce the rules with glee!

It's a pity really, never forget the officals and legislators work for US the people.

Ahh! another cynic like myself!
But we must remember he is simply setting himself up for that post PM American Lecture circuit that will earn him millions.
Why else would he suck up to W
