When did our liter (1000cc's) become an American quart?

American measurment of liquids came from our American system of weights. With most liquid measurements of light products (milk, water, etc). 16 fluid ounces of a product is also 1 lb in wieght. From this, the pint, quart, gallon, etc was born.

As far as gasoline goes, several stations in the US have been busted for installing substitute computer chips inside their pumps that short the fuel purchase, except when a certain amount is pumped (such as when inspectors are testing the pumps).

If you think your gasoline station might be doing this, report them to the appropriate government agency. In the US state of Florida, the Department of Agriculture and Consumer Services oversees all commercial scales and fuel pumps.

Sure, I've run into a bad meter on a gas pump. I was able to put 48 gals into a 36 gal. tank. I wrote down the pump number, certified seal number, and had a fuel receipt printed. I then called the "Arizona weights and measures" and filled a complaint. Lucky the pump was visible from the shop from where i work and saw the State truck pull up. Why, i never did get a refund--they shut down the station from selling fuel for 20 days, and they paid a heavy fine----because the meter was altered. If the meter was not altered then they would have just gotten a warning and could continue selling fuel on their other pumps. I'm sure in Canada there is a way of filing a complaint.

Not sure entirely what it is your alluding to but I'll take a crack at it. If you're converting from US standard to the Imperial equivalent you need to remember there is a difference. An imperial gallon comes out to a pint more than a US gallon or there are 4.5 gallons imperial to the standard 5 gallon US gas can. A gallon of paint in the US is the equivalent of 3.78 litres. But if you purchased 10.12 litres at say PETROCAN and it measured out to be 8.87 litres at home then you did get hosed and it's probably due to the fact that they haven't corrected the volume settings for the colder weather. But that's still a fair difference. Hope that helped.

In the US, the Federal Bureau of Weights and Measures regulates this, and gas stations have to get tested every so often (I forget the interval), so I would look into if there is a similar government entity in Canada, and nail 'em.

definite, I even have! no longer purely do I stay purely a quick sail from Canada, I even have some Canadian friends that often urge me to flow the border, yet... properly, i'm a Detroit grrrl, and the only plans I could bypass to Canada superb now are interior the form of a nuclear attack or some such BS and then I head for the Hudson Bay. via Canada, and up. way up. rattling, my passport isn't as much as date nonetheless!
