Should a fraction of an ounce be abbreviated as "ozs." or "oz?"
This week's Coin World has a nice write up on Roger Burdette's new book on the Saudi gold disks of the 1940's and other tales about the U.S. Mint. In the writeup there is this illustration of a "One Pound" Saudi gold disk, the picture courtesy of Heritage Auctions.
The weight is given as ".2354 TROY OZS." The Editor in my bones questions whether a fraction of an ounce should be given a plural abbreviation. Why not ".2354 TROY OZ.?"
Is there an English Teacher amongst us who can comment?
