AbbreviationsDate: Thu, 01 Dec 1994 08:54:57 -0500 From: Anonymous Subject: Math question Dear Dr. Math, Our junior high math classes understand how most abbreviations in math can be explained. For example, qt. = quart; in. = inch; and oz = ounce. But how did we get lb. for pound? Thank you for your time.

The abbreviation for pound comes from the Latin word _libra_, which was a unit of weight roughly equal to 3/4 of a pound. Some related words are the zodiacal sign "Libra" (the scales, or the balance) and librarian. Just kidding about the librarian. That's from the latin root _liber_, meaning "book." -Ken "Dr." Math |
