The common calculation formula for Chinese rebar is: weight (kilograms) = diameter (millimeters) × diameter (millimeters) × 0.00617 × length (meters). For example, to calculate the weight of rebar with a diameter of 20 millimeters and a length of 12 meters:
- First calculate the weight per meter according to the formula, (kilograms/meter)
- Then calculate the total weight of 12 meters, (kilograms)
