weight of all steel can be calculated by multiplying unit volume with density.

DxD/162 this is the formula for finding unit weight of steel
The unit weight of Fe 500 grade steel is approximately 7.85 kg/m^3, while the unit weight of Fe 450 grade steel is also approximately 7.85 kg/m^3.
6.568 kg/m
16mm dia weight for running feet
The weight of steel is typically measured in pounds (lbs) or kilograms (kg) per unit length, area, or volume. To calculate the weight of a specific amount of steel (e.g., 38 mm in length), you would need to know the density of the steel and apply the appropriate conversion factors.
No set answer to that, as steel pipes come in various diameters and wall thicknesses. If you want to be real accurate, they also come in various steel alloys, which do have some difference in density between them.
