It surprised me when we recruited a developer from Canada, and on his second day at work he asked what temperature he should have set the oven to. I learned that Canada has appliances labelled in "American".
180°C is the most common oven temperature required, outside 160-200°C is unusual for normal cooking.
There's a surprising inconsistency in Canada for units because of our proximity to the US. For body weight and height, nearly everyone uses lbs and feet/inches, but official records (on my driver's license for example) uses kg and cm. Like you said, most appliances are F. Distances are in km but property sizes are still often in sqft (because lots of products come from the US). The list goes on.
I was having an online discussion with someone in an electronics forum the other day, and we were talking about the ideal temperature for a soldering iron for a contact point using a particular type of solder and potentiometer.
He kept talking about setting the iron at 300 degrees. Now, my iron DOES have a setting up to 400 degrees, but in Celsius. He was talking in Farenheit, and had I not double checked with him, I would have fried my electronics to a crisp.
Warming (180-200F)/90C
Low 300F/150C
Med 350F/180C
High 400F/200C
Broil
Huh? I probably do more than 50% of my cooking outside that range.
I gave the temperatures based on my experience of cooking "normal" things, like roast meat, roast vegetables, chips, bread and cake.
They happen to correspond to Wikipedia's idea of "Moderate" temperatures:
Although, I've never owned an oven without a fan-assist.
(And for what it's worth, Tesco's frozen pizza and chips should be cooked at 180°C and 200°C respectively, or 200°C and 220°C without a fan oven.)
