Fuel consumption/ fuel effinciency

Miles per gallon, it's the "standard measure" of fuel consumption in the UK although the kilometre is much more widely used than the gallon. (making a metric measure more sensible!)

But I don't care about miles per gallon...

So,

in civilised terms, fuel consumption is measured in litres per 100 kilometres. (L/100km)

is this really practical?

Most British car adverts show fuel consumption in L/100km (unfortunately most times in brackets and in small print).

but why not kilometres per litre? (km/L)

personally, I think km/L is simpler to get to grips with, and more practical because you know that you'll drive y km using x L of petrol at a given fuel consumption.
(y/x km/L). eg. 6 km on 2 litres of petrol at 3km/L!

using L/100km is not as practical!


so why make life more difficult?

sure many people would rather switch to km/L rather than L/100km!


why not use km/L ?
...they do in Latin America and Japan!

Sorry for the lack of posting...

I had my heart set on going out and getting some shots of signs vandalised by the imperial-loving idiots, but unfortunately, my bike has been stolen. In light of this I bought a new one, and that was also stolen. So that has put a damper on me going around trying to get shots.
In the mean time i'll just moan about the notation of km/h again..

I was reading through one of my textbooks today and there was a question stating:
"suppose an advertisement for a new model of car states that it does an average of 12 kilometres per litre (kpl)at a speed of 80kph..."

You'd think that a university text book author at least would have the intellect to get it right?

Kilometres per litre, although not the most widely accepted metric form of measuring fuel consumptution (the more common one is L/100km) is a correct and accepted form, however why kpl?
quite clearly km/l (or km/L) clearly!

and again this kph rubbish... it's km/h for crying out loud!

maybe getting rid of rubbish like miles per gallon and miles per hour would help the situation?

speaking of which, who uses the gallon anyway?
