None. Concrete may be formed without metal.
If you are reinforcing the concrete with rebar then it depends on what loads the reinforced concrete will have to bear, the dimension of the rebar, the safety factor involved, and lots of other geometric factors.
Steel bars quantity will be according to structure element; but a (very) rough average of 120 KG per cubic meter.

The amount of steel required for one cubic meter of concrete in a six-story building typically ranges from 80 to 120 kg, depending on factors such as design, load requirements, and local building codes. For a standard reinforced concrete structure, a common estimate is around 100 kg per cubic meter. However, precise calculations should be made based on specific engineering designs and structural analysis. Consulting with a structural engineer is essential for accurate requirements.

It all depends on the type and sizes of the steel used. It also depends on the load that the concrete has to take at certain points. 7865kg is the weight of a cubic meter of steel. Typical examples; A pile cap could contain 400kg/m3 A heavy duty industrial slab or structure could contain 200kg-400kg/m3 A footpath could contain 40kg/m3 (all depends on the design, but numbers above should give you a rough answer)

The amount of steel reinforcement in a concrete retaining wall is typically measured in terms of kilograms per cubic meter (kg/m³). The exact quantity of steel reinforcement required can vary depending on factors such as the design specifications, load requirements, and the dimensions of the retaining wall. In general, a common range for steel reinforcement in concrete retaining walls is between 60 to 150 kg/m³, but it is crucial to consult with a structural engineer or refer to specific design guidelines for an accurate calculation.
A regular slab for residential loads around 250 - 300mm thick would be expected to be about 1.5 - 2% steel.
A cubic millimeter of steel weighs approximately 0.0000353 pounds. This is derived from the density of steel, which is about 7,850 kilograms per cubic meter. Since there are about 1,000,000 cubic millimeters in a cubic meter, the weight of one cubic millimeter of steel can be calculated accordingly.
