Solution to

Frame 4-42

Since 1 C = 1.8 F, it appears that to change a Celsius temperature

reading to a Fahrenheit temperature reading, you would simple multiply

37 C (or 37.0 C)

the Celsius temperature by 1.8. For example, 20 C x 1.8 = 36 F. If

you look at the thermometers in Frame 4-42, however, you will see this

98.6 F

is not so. What you have actually found is that 20 C above the freezing

point of water is equal to 36 F above the freezing point of water. Since

water freezes at 32 F on the Fahrenheit scale, 36 degrees above

freezing would be 36 F + 32 F, which is 68 F.

Remember: When converting from Celsius to Fahrenheit or from

Fahrenheit to Celsius, you must adjust for the different freezing

temperatures.

The formula for converting from Celsius to Fahrenheit is

F = ( C x 1.8) + 32

OR

F = 9/5 C + 32

When converting from Celsius to Fahrenheit, you multiply by

,

then add

to the product.

Solution to

Remember, when converting from Celsius to Fahrenheit, you **multiply**

Frame 4-43

9/5 (or 1.8)

32

Convert the following Celsius temperatures to Fahrenheit using either of

the formulas given in Frame 4-41. The formulas are the same except one

uses a decimal form (1.8) and the other uses a fraction form (9/5).

a. 0 C =

F

b. 100 C =

F

c. 38 C =

F

d. 212 C =

F
