ANSWER
16 cm = 160 mm
EXPLANATION

Next we have to determine the starting point. In this case it's the step of the ladder that says CENTI.
Then, determine the ending point - in this case MILLI, and count the jumps:
There's one jump, so now we have to move the decimal point in the same direction that number of positions:
If needed, add zeros.
Hence, 16cm = 160 mm
