Question

What is meant by a mil-foot section of wire?

Answer 1

>A mil-foot is a section of wire one foot long and one mil in diameter; this would be a unit of volume equal to about 0.0377 cubic inches or 0.6178 cubic centimeters.

However, the unit is used primarily in statements of resistivity in ohms per mil-foot or of density in pounds per mil-foot.

The unit is also called the circular mil-foot.

>A circular-mil-foot  is a unit of volume. It is a unit conductor 1 foot in length and has a cross-sectional area of 1 circular mil. Because it is a unit conductor, the circular-mil-foot is useful in making comparisons between wires consisting of different metals.

For example, a basis of comparison of the "RESISTIVITY" of various substances may be made by determining the resistance of a circular-mil-foot of each of the substances.

>1 mil =0.001 inch, or one-thousandth of an inch.
