In a scale 1 newton equals 1:250 and 5 m is equal to 1 m:50 N whenever both are represented with an arrow of 2 cm .
`` Thus there is typically consistency in scale among quantities of the same dimension , but otherwise scale ratios may vary ; for example , if `` '' 1 newton '' '' and `` '' 5 m '' '' are both represented with an arrow of 2 cm , the scales are 1:250 and 1 m:50 N respectively . ''
