General Information

The rebar sizes indicate the diameter of the rebar rods (see Rebar Specification table).  The default input length is feet, and the default output is in pounds, but both can be changed with the pull-down menus to any length (e.g. meters or miles) and any weight (e.g. kilograms, U.S. tons or Metric tons).

The length of rebar is multiplied by the pounds per foot, which is based on the size of the rebar (2-12,14,16,18,20).
