\nThe following is by my understanding.<\/p>\n
\nWhen I was a kid, gas was, at first, sold in cents per gallon, as I recall. Nominally, it was the same in the US: cents per gallon. However, it really wasn’t the same.<\/p>\n
\nIn Canada, we used imperial gallons. An imperial gallon is 20 percent larger than a US one. (The reason for that might be another post.)\n<\/p>\n
\nAs of around 1979, Canada switched to metric; therefore, one hardly ever hears about gallons unless it’s US gallons. The situation is emphasized by the fact that so many manufactured goods from the US reach here.<\/p>\n
\nI checked the water heater: its capacity is given as 40 US gallons on the decal. It also says 151 litres.<\/p>\n
\nThe gallon is a fantastic unit that, to a Canadian, can reach back to pre-metric times. The US gallon, by its name “gallon,” can still bring on that nostalgia, even though it’s not the same:)<\/p>\n
