Knots and miles per hour

Chicago August 28, 2001 Tuesday, 0900

Tom Skilling, chief meteorologist at WGN-TV

Dear Tom,

Your column today (Tuesday, August 28, 2001,)answering a reader's question about the relationshipof knots and miles per hour says:

"One knot means one nautical mile per hour and isequivalent to 1.1508 statute miles, our common unit ofmeasurement."

One knot certainly means one nautical mile per hour,and one nautical mile means 1.1508 statute miles, butone knot is not equivalent to 1.1508 statute miles;one knot is equivalent to 1.1508 statute miles perhour.

Your column is just about the first thing I read inthe Tribune every day. Keep up the good work.
