-6F = -21.111...C
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.
