Variations due to stretching or softness of the material are to be ignored. An example of rolled material would be a rolled carpet or a rolled sheet of paper from the paper mill. The length units that can be used are yard, feet, inch, meter, centimeter, millimeter and mil. A mil is equal to one thousandth of an inch.
