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.
