How do you know which unit of conversion factor must be in denominator?
Here is an example of a unit conversion. You want to convert, say, 10 feet to inches, and you know (or look it up) that 1 foot = 12 inches. What you have to do is to multiply either by (1 foot / 12 inches) or by (12 inches / 1 foot), since either of this is equivalent to multiplying by 1 - in other words, the result won't change (it will represent the same measurement). If you multiply by (1 foot / 12 inches), you get units of square feet divided by inches - not very useful. If, on the other hand, you multiply by the reciprocal, i.e., (12 inches / 1 foot), the feet cancel, and the only units left are inches. In summary, you put the unit of the ORIGINAL measurement into the denominator, to make them cancel. Or just try it both ways, and see in which of the two options the units cancel.
