Answer:
We have the equation:
(14 N/mm)*X = Y N/cm
So we want to transform 1/mm to 1/cm.
We know that:
10mm = 1cm
1 = 10mm/1cm (we want to have mm on the numerator, so it cancelates with the mm in the denominator)
then the conversion is from 1/mm to 1/cm is:
X = 10mm/cm
then we have:
(14N/mm)*(10mm/cm) = 140 N/cm
