How do you know when to multiply and when to divide to convert units of measurement?

Try both, and check in which of the two cases the units cancel. Here is an example:
1 km = 1000 m. Therefore, 1 km / 1000 m = 1, and also: 1000 m / 1 km = 1.
To convert 3 km to meters:
* If you multiply 3 km by 1 km / 1000 m, you get units of square km / meters (doesn't work, the units didn't cancel)
* If you multiply 3 km by 1000 m / 1 km, some of the units cancel, and you get only m in the result (this is the correct way to do it).
