Rebar Weight Formula?

Exmaple:-

There is another way of calculating the specific weight (or unit weight) of a rebar. Especially for those who are interested of rebars less than 10mm of dia.

the way is to calculate it mathematically knowing that the
Note:-
a.] Density of steel rebars is 7851 Kg/m3.
b.] 8mm Diameter Rebar

A.] Formula:-

Unit weight [Kg/m] = Cross-Sectional Area [m2] x Density [kg/m3]

B.] Answer:-

Unit weight [Kg/m] = (22/7)x(radius)2 x 7851 kg/m3
Unit weight [Kg/m] = 3.14 x 16 x 7851 kg/m3
Unit weight = 0.395 Kg/m

8mm dia 1m weight = 0.395kg

Weight of Rebar = .0395[Kg/m] x Rebar length

8mm dia 3.66m length Rebar Weight ?
= .0395[Kg/m]x 3.66 [m]
= .14457[Kg]

In foundation design, while we do the base pressure check, we normally check if the attained pressure value is less than the GROSS BEARING CAPACITY of the soil which is the sum of net bearing capacity of soil and the overburden pressure. Actually, the overburden pressure acts against the net bearing capacity of the soil and I feel that we are actually increasing the bearing capacity value and doing the check. I feel that this is NOT right. Please clarify on this.
