In creating a unit conversion factor, start by listing the current units and the units you want to convert to, such as converting meters to kilometers.
The initial step in forming a unit conversion factor is to identify the units you currently have and determine the units you wish to convert to. For example, if you are starting with units in meters, and you need to convert them to kilometers, this becomes the basis for your conversion factor. The conversion factor will be constructed so that it cancels out the original unit (meters) and introduces the desired unit (kilometers).
To identify which quantity goes in the numerator or denominator of the conversion factor, consider whether you are converting from smaller to larger units or vice versa. Since we are converting meters to kilometers, a smaller unit to a larger one, you will use a conversion factor where meters will be in the denominator and kilometers in the numerator to ensure meters cancel out.
To effectively use conversion factors, whether for converting units within the metric system or to move between different U.S. customary units of length, mass, and capacity, you will often multiply or divide by the conversion factor. This process is part of dimensional analysis, a method where ratios and conversion factors help you transmute units correctly while ensuring units that aren't part of your answer get canceled out.

The first step in creating a unit conversion factor is to determine the units you are starting with and the units you wish to convert to. This involves identifying the given and desired units, establishing a relationship between them, and creating appropriate conversion factors. Proper construction of the conversion factor allows for correct unit cancellation during calculations.
