The units go this way.

deci

milli

Move the decimal point to the left when moving UP the scale. Move the decimal point to the right when moving DOWN the scale. For example, 240 mm to cm, put your pencil on the decimal point; i.e., 240., then count from milli to centi. That is 1 place so move the decimal point to the left 1 place and the answer is 240 mm = 24.0 cm.
