How about this sentence-The king decided to give him a ton's weight of gold.I have not seen it used in a sentence.I saw it in a book, in the part about possessive nouns.
They were emphasizing about the use of apostrophe. I quote " words denoting weight, if it is followed by the word 'weight' after it. For eg. a ton's weight,a gram's weight, a pound's weight. "
