Here is a word that I see quite often in British writings, but as an American, I am not familiar with it. I mean, I know what a rock is, but what does a British author mean when he uses the term “stone” for weight. I finally looked it up because I found it in “The Missing Three-Quarter” in The Greatest Adventures of Sherlock Holmes.

Stone – British unit of weight for dry products, generally equivalent to 14 pounds, though it varied from 4-32 pounds for various items over time

Usage: Mr Cyril Overton, sixteen stone of solid bone and muscle, who spanned our doorway with his broad shoulders. (Roughly, about 224 pounds.)

(I believe the sport referenced is soccer, as later in the story “football” is mentioned.)
