When going from larger to smaller measurements, there will be more of them so it is necessary to multiply.
1 meter = 100 centimeters
When going from smaller to larger measurements, there will be fewer of them so it is necessary to divide.
100 centimeters = 1 meter

That depends on what you are converting from. If you are converting from larger units, you multiply. If you are converting from smaller units, you divide.
F to C: Deduct 32, then multiply by 5, then divide by 9 C to F: Multiply by 9, then divide by 5, then add 32
Multiply by the factor for converting the large unit to the small unit or divide by the factor for converting the small unit to the large unit.
Convert all measurements to feet, then multiply. Or multiply first (that will give you the area in square inches), then divide by 144.

A kilometer is equal to 1000 meters. If you are converting meters into kilometers, divide by 1000. If you are converting kilometers into meters, multiply by 1000.
You would multiply, not divide, by 1,000,000
It could be either, depending on whether you're converting to a larger or smaller unit.
