A stone is 14 pounds...
A hundred weight (CWT) is 112 pounds
The English ton is 20 CWT or 2240 pounds...
I’m wondering why they put that fish back into a freshwater river ???
it could attack people...
My uncle used to scuba dive at Smith Mountain Lake in VA....It's a pretty large (20,000 acres) man-made lake. He said that, while diving one afternoon, he ran into a catfish that very easily could have swallowed him.
I wouldn't put it past Unc to embellish a tale or two, however, he stopped diving in the lake that day. You can make the call on whether or not to believe him.
