Hmm, which exact weight would that be? 0.5 kg or 500 mg? 0.5 kg = 500,000 mg, not 500 mg. :? Using different units of weight can get confusing. As kilograms are the units of weight you use in all of your questions, we'll use kilograms.

For further calculations, we need a weight per linear unit of length. Since the bar is 22 inches long, inches is a logical choice. Divide the total weight of the bar by the total number of inches. This gives us the weight per inch.

0.5 kg / 22" = 0.022727 kg per inch

1 foot long iron bar.

12 inches * 0.022727 kg per inch = 0.27727 kg

The size of one KG (1000g) bar.

1 kg / 0.027727 kg per inch = 44 inches long

(15.3kg = Length: ???)

15.3 kg / 0.027727 kg per inch = 673.2081 inches

(12ft 6in. bar = weight:?? )

18 inches * 0.027727 kg = 0.40909 kg
