The US system of referring to “sticks” of butter as a unit of measure is very frustrating. More frustrating is the fact that I can never remember how much butter is in a stick and so I have to look it up everytime.

I’m not very fond of tablespoons as trying to use volume to measure chilled blocks isn’t particularly sensible either, in my opinion. The simplest is weight.

1 stick of butter is the same as 8 tablespoons of butter.
8 tablespoons of butter weighs 4 ounces (113 grams).
1 tablespoon of butter is 14 grams.

1/2 cup of butter = 1 stick = 8 tablespoons = 4 ounces = 113 grams

2 sticks of butter is 8 ounces which is 226 grams which is most of a 250g block of butter as bought in Europe.
