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
o
o
o
o
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
o
o
98.6 F
is not so. What you have actually found is that 20 C above the freezing
o
point of water is equal to 36 F above the freezing point of water. Since
o
water freezes at 32 F on the Fahrenheit scale, 36 degrees above
o
o
o
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
o
o
o
o
o
o
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.
