stupid scoop question

I have two supplements, they both came with a scoop thats about the same size. However, a scoop for one of them says its 27g and the other says 43..i noticed they also have a line on the scope goin around the outside...but there is no numbers so i didnt know if this was just how its made or if im suppose to go by the line...or use a full scoop?
 
one of these is sizeon which i know people here use so that might help...
 
i have no way of wieghing it so which one is it?
 
am i dumb?

lol its usually a whole scoop, it wont do you any harm if you go over. rather over than under if your thinking of gainining mass. there never going to be spot on.
