Assuming you are talking about stoichiometery a conversion factor is often a number with two units. For example a conversion factor could be Miles per hour (Miles/hour). If you had miles and needed to convert to hours you would multiply the miles by Hours/miles so that the miles would be canceled out (miles/miles = 1). Then your units left would be hours. Or vice versa. There are other factors like this in chemistry like grams/mol Mol/liter etc. To put it shortly the conversion factor denominator is always paired with the numerator.
The numerator must contain the unit INTO which you are converting.
It is the units for the measurement which you are converting FROM.
The unit that is used in the denominator is the one to cancels the unit that appears in a numerator.
It must be the unit of the measurement that you are converting FROM.
These are the units which are used for the measurement that you are converting FROM.
The denominator must contain the unit that you wish to cancel in the numerator of the other number.

You need to know the conversion factor for the two units you are using.
A conversion factor is the same as multiplying by a factor of?
"I had to use a conversion factor to get the right unit for my answer on my chemistry quiz."
That's two words, you know. Conversion factors are just math quantities that you use to convert one unit into a different one.What's the conversion factor for changing inches into centimeters?
