How many g in 1 stick of butter?

In the rectangle blocks its usually 250, square blocks 500g.

NOTE: I am "improving" this answer because it must have been given by someone living outside the U.S. In the U.S., sticks of butter are shaped differently in different regions (shorter and fatter in the South, longer and skinnier in California), but they are all 113.5 grams. Commercial butter is not packaged in blocks of 250 grams in the U.S.

Not to mention that we count in ounces, not grams!
