This is a sort of proportion, because if a weight in pounds is changed in a certain number of times, then this weight in Newtons is changed in the same number of times.

1 pound = 4.45 N, how many pounds are in 1 N? Denote this quantity as x.


1 pound : 4.45 N = x pounds : 1 N,



By the property of proportions

`x = (1*1)/(4.45) = 1/4.45 approx 0.225 (N).`


(actually, 0.22 is more accurate number than 0.23)
