I’m not misunderstanding metric prefixes, you’re misunderstanding my point. When I say “Nobody uses calories” I mean “People don’t use the unit calories”. The way you don’t use millimeters when describing someone’s height. Or light-years. Yes, it’s just a simple conversion, but nobody uses it. America uses “Calories” with an uppercase C which is 1000 calories. Other countries use kilocalories which is also 1000 calories.
The thing is that most people don’t know Calories and calories are different so generally speaking if someone says calories they mean Calories.
