Weight of concrete reinforcement bar 12 MM diameter x 10 M?

To calculate the weight of a 12 mm diameter, 10 m long concrete reinforcement bar (rebar), you can use the formula: weight (kg) = (length in meters × diameter in mm × 0.00617). For a 12 mm diameter bar, the weight would be approximately 0.74 kg/m. Therefore, for a 10 m length, the total weight would be about 7.4 kg.
