Given:

Steel pipe weighs = 5 pounds per foot.

Question asked:

How much does it weigh in kilograms per meter ?

Solution:

We will convert foot into meter and pound into kilograms.

1 foot = 0.305 meters

1 pound = 0.454 kilograms

5 pounds =
`5*0.454=2.27\ kilograms`

By using unitary method:

0.305 meters of steel pipe weighs = 2.27 kilograms.

1 meter of steel pipe weighs =
`(2.27)/(0.305) =7.44`

Therefore, it weigh in kilograms per meter is 7.44
