The Pound Sign
Date: 04/06/2001 at 23:46:03 From: Mary Yarnold Subject: the correct symbol for "pound" weight Dear Dr. Math: I hope you can answer this question for me. My friend says that you can use this sign "#" to mean pound, but I disagree. Her reasoning is that it is called the pound button by anyone using a touch-tone phone. I have always believed that the symbol lb. is correct for this weight abbreviation. What do you think? Sincerely, Mary Yarnold
