Canadian dollars per litre
On a website, I saw a reference to the price of gas as 1.279. Initially, I didn't get it. Then I realized I was on a Canadian website and it was a reference to Canadian dollars per liter. So what is that in US dollars per gallon? And how do I figure it out without having to do two calculations, one for liter to gallon and another for the currency. Google, of course. To use my example, type: 1.279 CAD per litre in USD per gallon and click "Google Search". When I did it at noon on August 11, the result was "1.27900 (Canadian dollars per litre) = 4.58349234 U.S. dollars per US gallon". By the way, it doesn't matter if you spell it "litre" or "liter". What you will need is the three-letter code for currency, which you can find several places, including here , one of the sites noted on this website . More about Google's unit conversions here .
