can dimensional analysis be used to convert one system of unit to another system?
that one unit is converted into another. The basic idea behind dimensional analysis is as follows:
proceed with the rest of the problem.
EnglishâtoâEnglish, Englishâtoâmetric, or equivalence conversion factors such
as speed or density.
cancels out the unit you have. Continue in this manner until you have the
km. Lets look at this problem with the above steps in mind.
In this problem the given unit is âkm.â We are given 22.4 km.
In this problem we are asked to find this distance in inches. âInchesâ is the
unit we need.
We will need the following conversion factors:
1 km = 103 m 1 cm = 10â2 m 1 in = 2.54 cm
