FWIW - 100 degrees Fahrenheit used to be referred to as "the ton" before we in Oz went metric. Hence when the weather was hot one said, "It's going to hit the ton today".

Nowadays, 38 degrees C is often referred to by those of us that dwell in the past as being "the old ton".

In cricketing circles, when not using the more correct form of "a century" in reference to 100 runs, one may hear that such and such a batsman "hit (or got) a ton". Never "the" ton.
