The Strange History Of The Fahrenheit Scale

Ever wonder why the Fahrenheit scale was created so that water freezes at 32 degrees and boils at 212 degrees? You might find this article at The Straight Dope interesting (and hilarious.)

Pound = lb. and Ounce = oz. Why?

This is one of the questions that kept me wondering, but not enough to actively look for the answer. Today, my RSS feeder found a short article by the World's Smartest Human Being, Cecil Adams:

"Lb." stands for libra, the basic unit of Roman weight, from which our present-day pound derives. The libra weighed a little under 12 ounces avoirdupois.

"Oz." stands for the Italian onza, ounce. It came into use in the 15th century. Ounce comes from the Latin uncia, a 12th, which is also the source of the term "inch."

Of course, in the end, it does not explain why pound comes from pondo while lb. comes from libra. I guess random accident of human decisions got stuck with us again.

I have read the Straight Dope in physical book format since 1987 and found it very interesting. You might want to visit the website.
