Hello.
The conversion formulae are:
°C = 5/9 (°F - 32)
°F = 9/5 °C + 32
see:
Convert Me: Celsius and Fahrenheit
http://anduin.eldar.org/~ben/convert/c_f.html
1. So 98.6 °F ....
°C = 5/9 (98.6 - 32)
°C = 5/9 (66.6)
°C = 37
So "2 to 4 degrees C below 98.6" would mean 33 to 35 °C
33 °C = 91.4 °F
35 °C = 95 °F
---------
"for every 1.8 degrees that temperature changes on the Fahrenheit
scale, temperature will change 1 degree on the Celsius scale. Thus the
ratio of Fº to Cº is 1.8 : 1 "

2. Thus, an increase of 2.6 degrees Celsius would be the equivalent of
an increase of 4.68 degrees Fahrenheit.
(i.e., 2.6 * 1.8 = 4.68 )
----------
3. An increase of 2.8 degrees Celsius would be the equivalent of an
increase of 5.04 degrees Fahrenheit.
(i.e., 2.8 * 1.8 = 5.04 )
----------
4. 70 °C = 158 °F
As mentioned above:
°F = 9/5 °C + 32
so
°F = 9/5 (70) + 32
°F = 126 + 32
°F = 158
-------
5. As mentioned above, an ncrease of 1 degree C = 1.8 degrees F
-------
6. An increase of 2.9 degree C would be the equivalent of an 5.22
degrees Fahrenheit.
(i.e., 2.9 * 1.8 = 5.22 )
----------

I hope this helps. If anything is unclear, please request clarification. |

Sorry for that typo:
"5. As mentioned above, an increase..."

Thank you.
For future reference, I am still unclear on how to use these
converters, including the one you gave me below.
I plugged in 2.6 C to ? F and got:
Results:
Celsius: 2.6
Fahrenheit: 36.68
NOT 4.68 ! ! !
OK, I'm a writer, not a numbers person ... but I just don't get it! I
know your answers are right, I'm just dumbfounded.
Thanks again,
Susan
Answering is optional. Thank you again.

Ah, I think I see your problem.
You're mixing up converting a FIXED temperature with converting a
marginal temperature CHANGE. Two different things...
Try thinking about it this way:
0 degrees Celsius is equivalent to 32 degrees Fahrenheit.
See the two thermometers on this page:
http://www.internet4classrooms.com/F2C.
Now, would it make any sense to say that a CHANGE of 0 degrees Celsius
was the equivalent of a CHANGE of 32 degrees Fahrenheit? Of course
not! A change of zero is no change at all.
Sure, when the temperature is exactly 2.6 degrees Celsius, the
equivalent is Fahrenheit temperature is 36.68. But that's a different
issue from an INCREASE of 2.6 degrees Celsius.
Again, the key point is that for every 1.8 degrees the temperature
changes on the Fahrenheit scale, the temperature will change 1 degree
on the Celsius scale.
Try plugging in some numbers...
For example, convert 10 degrees Celsius to F, and then convert 11
degrees Celsius to F. You'll notice that the marginal increase of 1
degree Celsius is the equivalent of a 1.8 degree increase in the
Fahrenheit temperature.
I hope this helps.
