When The Celsius Temperature Changes 10 Degrees, How Much Does The Fahrenheit Change?

Fact:
0 degree Celsius = 32 degree Fahrenheit
The formula for conversion is:
Tc = (5/9)*(Tf-32)
Where:
Tc = temperature in degrees Celsius; and
Tf = temperature in degrees Fahrenheit
So 20 degrees celsius would be:
10=5/9 * Tf  - 32
10 + 32 = 5/9 *Tf
42=5/9 * Tf
42*9=5*Tf
378=5*Tf
Tf=378/5
Tf=75.6
So 10 degree Celsius = 75.6 degree Fahrenheit

When Celsius changes 10, Fahrenheit changes 18.

Examples:
-40C = -40F
-30C = -22F
-20C = -4F
-10C = 14F
0C = 32F
10C = 50F
20C = 68F
30C = 86F
40C = 104F
50C = 122F

There are 4 easy ways to convert from one temp to another using a calculator (unless you can multiply and/or divide in your head).

C: Celsius
F: Fahrenheit
+: Plus
-: Minus
x: Times
/: Divided By
=: Equals

To convert from C to F:
C x 9 / 5 + 32 = F
C + 40 x 9 / 5 - 40 = F
C x 1.8 + 32 = F
C + 40 x 1.8 - 40 = F

To convert from F to C:
F - 32 x 5 / 9 = C
F + 40 x 5 / 9 - 40 = C
F - 32 x .5555556 = C*
F + 40 x .5555556 - 40 = C*

*The last 2 equations will never give you an exact temp.  The larger the number, the less accurate it is.  This is because .5555556 is actually .555...  For practical purposes with normal temps, just round C to the nearest number.
