The measurement is likely to be in feet and inches, or in metres and centimetres.
I would use a centimetre to measure the length of a boy. Not sure what a boy yard is, though.
It depends. There is no fixed height for anyone.

5'10 to 6'4
It depends with he genetic genes of the family. A boy of 10 years should be of a height of between 51 ans 59 inches.
It is not possible to estimate the adult height of a boy from his height at the age of 10 because children have growth spirts at different times as they age. Generally, the adult height of a boy will be twice his height at the age of 3 years. The adult height of a girl will be twice her height at the age of 2.5 years. This is always assuming that no debilitating disease or genetic condition is present to alter the situation.
