15. Stair Step Method  A short cut that may also be used is the stair step method.

16. When converting from one unit to another: 1. Move the decimal ________ space for ___________ step taken on the stair case. 2. Move the decimal to the ___________ if you go ________ the stair case. 3. Move the decimal to the ___________ if you go ________ the stair case.

17. Example- Convert the following: 1) 10 hm= ____________ dm?  Moving from the h-step to the d-step requires three steps to the right on the staircase.  Therefore, move the decimal three places to the right.  Answer: 10 hm = ____________ dm

18. Example- Convert the following: 2) 5 cL= ____________ dL?  Moving from the c-step to the d-step requires one step to the left on the staircase.  Therefore, move the decimal one place to the left.  Answer: 5 cL = ____________ dL
