Of all the weird US measurements, I find their measurements of butter to be the strangest. They usually refer to it as cups or sticks, or worse, tablespoons. How do you measure a table spoon of butter, and WHY on earth WOULD you do that?!!!
Most butter wrappers come with weight graduations, or if not its easy enough to guesstimate the weight by dividing a block evenly.
Anyway, I found out this information:
1 stick of butter = 1/4 pound
1 stick of butter = 1/2 cup
1 stick of butter = 8 tablespoons
1 stick of butter = 4 ounces
1 stick of butter = 113 grams
So, by extension, 1 cup of butter = 227 grams (the almost standard size of one block these days...eg anchor butter, is 227gm instead of 250gm), and 1 cup butter = 16 tablespoons.
While we're at it, those of you who don't have a digital scale, might wonder how to measure 7g of yeast. Aside from going to the post office and asking them to weigh for you, ....hmmm, I found out that 7g of yeast is 2 teaspoons. Although recently I have been given a digital scale, I haven't bothered to verify.
