Date: 04/21/2002 at 10:56:06 From: Doctor Sarah Subject: Re: Linear Footage Hi Pat - thanks for writing to Dr. Math. It's 50 feet long. A linear foot is a foot in length. From Russ Rowlett's _How Many? A Dictionary of Units of Measurement_: http://www.unc.edu/~rowlett/units/dictL.html linear foot (or "lineal" foot) (ft or lf) terms used loosely to describe a one-foot length of any long, narrow object. The correct term is linear foot; the word "lineal" refers to a line of ancestry, not to length. Boards, pipes, and fencing are typical objects measured and sold by the linear foot. In the moving industry, a linear foot is a one-foot length of a moving van, usually a volume of about 72 cubic feet (roughly 2 cubic meters). Occasionally the term "linear foot" is used as an alternate name for the board foot, but this is appropriate only if the board is 12 inches wide. Terms such as linear meter and linear yard are used in a similar way to indicate one-meter or one-yard lengths. - Doctor Sarah, The Math Forum http://mathforum.org/dr.math/
