Eleven standard sizes of reinforcing bars are in use rebar could be procured locally and could be metric. today. Table 7-1 lists the bar number, area in square Table 7-3 is given for comparison. Remember that bar inches, weight, and nominal diameter of the 11 standard numbers   are   based   on   the   nearest   number   of sizes. Bars No. 3 through 11 and 14 and 18 are all one-eighth inch included in the nominal diameter of deformed bars. Table 7-2 lists the bar number, area in the bar. To measure rebar, you must measure across square inches and millimeters, weight in pounds per foot the   round/square   portion   where   there   is   no as well as kilograms per meter, and nominal diameter of deformation.  The  raised  portion  of  the  deformation  is the  8  standard  metric  sizes.  At  various  sites  overseas, not measured when measuring the rebar diameter.
