Explanation:
The units from Biggest on the left to smallest on the right are:

When you convert a value to a bigger unit, the number gets smaller. (There are fewer of them.) This is done by dividing
When you convert a value to a smaller unit, the number gets bigger.(There are more of them.) This is done by multiplying.
Km is the biggest distance of the metric system. (Just more than half a mile.)
mm the smallest of the usual lengths in the metric system.
(About 25 mm makes 1 inch)
To convert 3 Km to mm, write 3 under Km and fill in a 0 under each of the other units
The decimal point shows what the unit is.
