For calculating the weight of bars we can use this formula
Just keep in mind that , while using the above formula, the unit for Diameter is millimeter (mm) while that of Length is meter(m).
and the unit of weight is kilogram (Kg).
And also note that for calculating weight of bars/ reinforcements of different materials (other than mild steel), the density part must be changed accordingly.

What is the nominal weight of standard concrete?
How heavy is concrete?
The weight of concrete can vary slightly depending on the mix type.
The most typical value widely used is 150 lb/ft^3 for the most
common/ordinary concrete strength at ~ 4,000 psi = 4000 lbf / (sq in).
The aggregate used, strength of concrete and how thin or semi dry the
concrete is prepared are the aspects for concrete weight. Even though
the aggregate is denser and heavier than water (4 parts of the aggregate
is contained within the concrete - add 1 part dry cement + water, 4:1
always in volume sense is the usual standard concrete mixing
ratio), wet fresh concrete before it sets will not be much heavier nor
lighter per volume unit because the water presence is adding to its
total weight. Though, to be exact, there is the marginal drying
shrinkage caused by the water evaporation from the fresh concrete which
causes a slight weight difference between the soft and set concrete
