Weight of 25 linear meters = 25 * 25 * 0.0017 = 3.85kg.

22 linear meter weight = 22 * 22 * 0.0017 = 2.98kg.

25 Weight of threaded parts = 3.85 * 9m * count/1000 (ton), with three decimal places reserved and rounded.

Another calculation method is rice weight = circular area * specific gravity of iron.
