Multiply the rebar diameter (mm) by 0.006 17 and then by the length l.

0.6 17 is the weight of circular 10 steel bar per meter. The weight of steel bars is proportional to the square of the diameter (radius).

G/m=0.6 17*D*D/ 100

Weight per meter (kg) = rebar diameter (mm)× rebar diameter (mm)×0.006 17.
