4.3 cm would be 1.69 in
Here is the simple metric table
km
hm
dam
meter
dm
cm
mm
So to go from cm to mm you move down the table 1 place which means you move the decimal point to the right 1 place.

Jean gave the answer of 1.69 but there are only two sig figures in 4.3 so the answer should be rounded to 1.7 inches.
