MPG - Imperial or US gallons?

When calculating mpg to you use imperial gallons or US gallons?

I get ~41mpg with Imperial and ~35mpg with US.

Imperial. I never even knew there was a US gallon until I was served what they call a pint over there...

It depends where you are! Normally we use imperial but nowadays people should be using litres/km, Europe & all that!

Aren't pints the same and its only gallons that are different?

Not a bad number of responses in 4 minutes!

Are you still a subject of the commonwealth? (get the feeling I really shouldn't ask that)

Well litres are a universal measurement.

At the pumps we use litres, and if Americans use litres at their pumps (I don't know if they do) then our calculated mpg will be different to an Americans.

Imperial, obviously. Silly question really. We're not in the US.

Nope, US pint is smaller.

In America, they say "A pint's a pound the world round" which is a silly mnemonic, since in the Empire "a pint of water weighs a pound and a quarter".

Not so silly. Their gallons are smaller therefore their mpg appear poorer than ours.

Yes I am aware we are not in the US. Last time a checked we weren't in the British Empire either :pac:

Yes since 1949, but to all intensive purposes we are still part of the UK anglosphere. Therefore given the influence (culturally, politically, socially, historically) its makes since we continue with what we know, which happens to be the Imperial weights and measures, and more recently the metric malarkey.

Do we spell like the yanks ? Do we call petrol gas ? No and no, when in school we are taught metric but often imperial too, a gallon is 4.54l ish when in Ireland. Silly question

Yeah, honestly, some people might want to get a clue and open a history book (or map).

wow, I suppose the :pac: smiley wasn't enough of an indicator that it was a joke.

Perhaps I'll wrap future non-serious statements in [non-serious] tags to let guys like you know the difference.

Am I the only one who thinks my silly question isn't silly at all?

Your original post wasnt a joke though was it!
What I think is "silly" is the fact you seem unaware that the Imperial System was (and continues in some quarters) the official unit of measure in the Republic of Ireland until the late 70s. At no point did we ever use American measurements (eg Cups, Fahrenheit and of course US Gallons). Honestly though, how did this even arise as a question?

Not all posters here are as old as you or me though

The younger generation was taught SI in school and think in it only. A change for the better methinks.

The question arises becuase mpg calculated in different countries leads to different answers.
I was merely checking to see if there was an unwritten rule to say you use a certain standard to get a globally uniform answer.

I don't appreciate the "we don't live in the US lolol olol olololol loll ol " type responses. Please don't try to make me out to be a fool who doesn't know what unit we use(d) in this country.

Why would anyone think that ?

The comprehension levels in here seem to be very poor.

Cookie_Monster · 11-05-2010 9:06am

are you using land miles or nautical miles?
That'll affect it too.

Very true, is there an unwritten rule to say you use one or the other to get a globally uniform answer ?

I think I may be younger than you think.

I was taught only metric in school, but am obviously aware of other measurement systems too.

It doesnt matter what you use as long as you do the calculations correctly. Most people here I would guess would use imperial gallons. Although the metric system is far far better and easier to understand, but thats another days ranting

Metric system is an awful lot handier but people have a more intuitive grasp of what a good mpg figure is, whereas not as many would know what a good l/100km value was

Of course the real answer is neither:

I visited Christian on Sunday after the match. He needed to run an errand so I offered to drive over to Julian's gaff to collect the gear for Tuesday night. I'd only filled it on the previous Thursday and even after returning home via the Outlet centre - they had some excellent specials on - the tank was still showing about a quarter full. On the Beemer, the light would have been on!

or maybe:

I was down in the mudders on Wednesday. She asked me to go and collect de washing from de sisters. I did dat and stopped off for chips in Pa's on de way home after calling into Charlie to talk to him about the sediment in the well. Drove to work the next day and I called back to Charlie in the evening (he wasn't well). I put a tenner in on my way back from work the next day and it brought up between a quarter and a half - dat's pretty good I'd say.

The only problem with this style of fuel consumption reporting is that it's somewhat, eh, subjective

My own yoke does :

29.25 Imperial MPG, which, divided by 1.2 = 24.37 US MPG, Or, using the formula 100/(Imperial MPG *.354) = 9.65 L/100kms
