A Rant About Sizing and Measurements

measuring cup

I must have been living in a hole, because until yesterday, I never knew that there was a difference between an American cup and a Canadian cup. It can't be all that much, since I've used the two interchangeably for years, but it has ruffled my feathers and made me wonder if all of my baking would've been just a little bit better had I known this earlier.

It all came on the heels of me trying to transcribe a recipe that had everything by weight. Personally, I like weighing my dry goods, but I like to throw in a cup here or there when it's a liquid. But now I have to watch my cups, and figure weight, and be sure that my calculations are for the right ingredients. I get the differences between measuring systems, and I grumble my way through density and volume, but this is something different. A cup can't be a cup if the two sizes are different! That's just silly -- especially in an age where we get recipes from all over the globe.

And I wasn't even going to write about it until I read that Haagen-Dazs was shrinking their pints from 16 ounces to 14 ounces. You can't shrink a unit of measurement! What's wrong with people!?

A pint is not a pint unless it's a pint! A cup is not a cup unless it's a cup!

So 1 imperial cup is ~7.7 US oz. That's about a difference of 1.9 US teaspoons or 9.3 mL. It really starts to add up once you go to gallons.

It doesn't surprise me that Haagen-Dazs is doing that seeing as how their parent company (Dreyers/Edys) did that with their "quarts" a LONG time ago; while I don't know if they call them "quarts", it is still assumed by most people that they hold the same as the ice cream containers that are comparable in price/size. Check it out next time you're in the ice cream aisle; they are not full quarts, whereas usually the store brands are.

Cheers!

If a recipe calls for a pint, there is a difference. A Canadian (Imperial is the proper name) quart is 40 ounces, and American quart is only 32 ounces. So a pint is 16 ounces US versus 20 ounces Imperial.

But if the measurements are cups, teaspoons, tablespoons etc.. there is no difference. The best way is to weigh which is why all Euro recipes are by weight-no mistakes then!!

Take a league, for example: the length of that varies all over the place. According to my reading, a "cup" is 8 fl. oz. in the US and 10 fl. oz. in the UK. And of course "ounce" is another of those unit problems (what with fluid ounce, avoirdupois ounce, and troy ounce). This is one reason that every nation on earth, with the exception of the US, Liberia, and Burma, every nation on earth has adopted the metric system of measurement. The problem is that the US lives in an international backwater in many ways (broadband speeds, for example, or no national healthcare system).

A dozen large eggs will likely include a dozen different quantities of egg. Different butter brands will have different fat contents. I'm no cooking student, but have decades of experience which have taught me not to sweat this stuff. It just doesn't matter. It may matter to culinary school teachers who use this stuff to terrify young chefs, control them and, as you suggest, make their heads explode, but in the real world? Not hardly.

A British pint is 20oz, though.

Metric doesn't go by the ounce, it uses millilitres for volume, and grams for weight.

1 US Cup 8 fl oz = 236ml or 1/4 quart
1 CAN Cup = 250ml or 1/4 litre

A 14ml difference, or nearly a tablespoon (which is the same across the board). I imagine that with some REALLY touchy baking recipes, this could have an effect, especially if you're using 4 or 5 cups of something.

But I find that as long as you use instruments using the same measurement basis (ie.- don't mix and match measuring cup sets), then there isn't a problem since the proportion tends to stay in line.
