Mileage conversion, UK or US

UK gallons are bigger than U.S. gallons. Most of us use U.S. gallons as default.

I use the same site when posting so those metrically challenged can relate.

In Canada, we used to use British units, so a gallon was 160 ounce (4 X 40 ounce quarts). We converted or switched to full metric way back in 1978, as I recall. I'm amused to see so many people here still ask for mileage in Imperial MPG. Most of them are too young to know what that is!

I prefer l/100 km. I wonder why Japan uses km/l? Any idea Ken?

 

The U.S. EPA obviously uses U.S. gallons! ... Though if they were using imperial gallons it would explain the inflated numbers they give to all cars (not just the Prius)! The MPG figures on the window stickers on cars sold in the U.S. are determined by the EPA itself. The manufacturers do not establish those numbers. (Though it would not surprise me if manufacturer lobbyists designed the tests that give inflated results.) I guess the tests have been changed for 2008, though, to give more realistic numbers.

 

Reasons I like L/100km
1/ When I fill up I devide the km I have driven by 100 which is as easy as moving the decimal 2 spots left then divide the litres purchased by that number to get L/100km
Example, I drove 870km on my last tank of fuel and bought 41.3 litres of fuel
41.3 divided by 8.70 = 4.747 L/100km
Simple
2/ I have a journey tomorrow to Melbourne 700 km from Adelaide so on my average fuel consumption I can calculate I will use
4.747 litres per 100 km
X 7 (hundred)
= 33.229 litres of fuel will be used.
Simple
3/ There is only one size litre in the world not 2.
4/ There is only one size kilometre even if you Americans spell it wrong. (I know there is only one size mile.)

 

A Nautical Mile is 6076 feet, and a Radar Mile is 6000 feet in comparison to a standard, or statute mile, which is 5280 feet. There are all sorts of "miles" . http://en.wikipedia.org/wiki/Nautical_mile

 

Also, just to clarify the EPA numbers. The EPA establishes the method that must be used to get the numbers, and requires all manufacturers who wish to sell in the US to do the measurement by that method. They then "spot check" to ensure nobody is cheating. Ditto for emissions.

I'm convinced the Canadian Govt. then takes the EPA numbers and converts them. That is, I'm convinced they don't redo the measurements. Vehicles that are only sold in Canada (and not in the US) do have to be rated for sale here, and again, it's by the manufacturer, spot checked by the Canadian Govt.

Note that the push is on here for California Air Resources Board or CARB emissions standards in Canada. Already two provinces enforce those standards, with more coming this coming year.

Say goodbye to the Smartfortwo diesel, say hello to the Smartfortwo gas model. Ditto for the other diesels (VW for example), except Mercedes, who inject a fluid to meet CARB standards.
