Most cars have this feature. A bit like most people won't fill their car up and calculate the fuel efficiency in metric or imperial on every trip to the petrol station unless they fear that something is terribly wrong and they believe that the figure they're getting is no where near the figure advertised or written in the guide book.

US cars don't, unless you own a luxury car. The rest of us have to calculate it if want to know it. So, how does the car know how many gallons or liters were put into the tank at a fill-up in order to calculate correctly? Do you key it in after the fill-up?

Do most people have the formulas memorized or do they have them written down? How do you calculate your fuel economy or do you bother at all? Why would you care about alienating yourself if all you are looking for is meaningful information on the economy of your car for your own knowledge? Unless you feel a need to broadcast the information. But from what I've read from the emails, even if you told everyone in metric units, they would still be understood. So how would you be alienating yourself? What do you mean by cc and ci? Are you talking about engine displacement? Presently all I ever hear is liters, never a mention of a cc or ci. That is the standard. I remember years ago motorcycles used cc, but I'm not sure if they still do or not. Do you own a motorcycle as opposed to a car?

A bit like if I converted my engine size from cc to ci.

Would it be just as easy to convert your miles to kilometers and figure it out completely in metric? It shouldn't make a difference which way you go. Maybe the best thing to do is to use the correct symbols as others noted.

I would be even less prone to want to do it if it meant an extra calculation step? Do people ever do miles per litre/liter if that would make it simpler to compute? Or is there a simple way to compute mpg when fuel is sold in litres/liters?" You'd think that miles per litre would have taken off here - but it hasn't. I guess there's a thought that there's consistency in keeping all units from one system. Or something. "I don't like this having to spell meter and liter two different ways. Which should I use?" I'd say the default was the American spelling - since this is an American board. I tend to use 're' due to force of nature. I think we know what we're all talking about - your best bet is to stick with liter/meter probably.
