How do you convert between Fahrenheit and Celsius temperature?


1. Form Entry...

Celsius:
Fahrenheit:
Kelvin:

2. The Equations...

To convert from Farenheit to Celsius, use this equation:

C = (F-32) x 5/9 ...or... C = (F-32)/1.8


To convert from Celsius to Farenheit, use this equation:

F = (C x 9/5) + 32 ...or... F = (C x 1.8) + 32

3. Using Your Head (deg. C to deg. F only)...

Here's a trick for converting Celsius to Farenheit in your head:

1) double the Celsius temperature
2) subtract one tenth of this value from itself
3) add 32

EXAMPLE: let's use 30 degrees C as an example.
1) double the Celsius temperature (2 x 30 = 60)
2) subtract one tenth of this value (60 - 6 = 54)
3) add 32 (54 + 32 = 86 degrees F)
