The 32 compensates for the fact that the Celsius scale uses zero as its reference point for the freezing point of water, but the Fahrenheit scale uses 32 as this reference point.

This value compensates for the different size of the two degrees. In the Celsius scale there are 100 degrees between the freezing point and the boiling point of water, but in the Fahrenheit scale there are 180 degrees to cover the same interval. The ratio of 180 to 100 is 1.8, so this correction factor is used in the formula.

This value compensates for the fact that the freezing point of water on the Celsius scale is 273.15 degrees lower than on the Kelvin scale. Since kelvins are the same size as Celsius degrees, no other correction factors are needed.

Notice that the student is not asked to solve the problem, but to explain the reasoning. Density can be used as a conversion factor because the definition essentially states that x g of substance is equivalent to

y mL of the substance. Therefore, the two conversion factors, and , can be written and the appropriate one used to make the desired conversion.
