I’m an American currently paying for the isolationist sins of my forefathers. I bought some food products from Australia and I’m trying to decypher the nutrition labels. Disclaimer: I’m somewhat “numerically-challenged” as the more sensitive among us like to say.
I have the basic metric stuff under control. What I need help with is joules, kilojoules, kcals, etc.
Basically, I’m used to seeing “energy” content on food packages measured in “calories,” and I’d like to convert the Australian info to calories. This Australian snack bar is unusual and quite amazing to me in a few ways. First, it has its label on upside down (sorry, couldn’t resist) and it shows energy in xxxx kj. Specifically, 1447 kj. As far as I can tell, that means “kilojoules”. All of the calculations that I’m doing, with help from Internet calculators, make me sure I’m screwing this up. See below:
If a calorie is equal to 4.19 joules, and a joule is equal to .001 kilojoules (or kj), then, what time will Train B get to the station? Sorry, flashback.
1447 kj = 1447 “1000 joules” = 1,447,000 joules = the family joules
1 joule = .24 calories, so …
1,447,000 joules x .24 = 347,280 calories
Therefore, at an average consumption rate of 2,400 calories per day for a man, that means that this one Australian snack bar can sustain me from now until sometime in September 2005 (144 days).
I’m beginning to suspect a couple of things: One, that I got a better deal on that snack bar than originally thought. And, two, in addition to being the rightful protectors of the English language, the Aussies might have the solution to world hunger as well.
