Write down the number that will be converted. Set up a conversion factor. Put the same unit as the number being converted on the denominator of the conversion factor. Write the base unit (meters, liters, grams, etc.) Place a “1” in front of the larger unit. Determine how many of the smaller units can go into the larger unit. Place this number in front of the smaller unit. Repeat steps 2 through 6 until the unit on the numerator matches the unit as the unit that you are solving for. Multiply the equation out. You may find it easier to multiple all numerators together and all denominators together to create a fraction. Follow this by dividing the numerator by the denominator.
