Celsius to Fahrenheit


Move along people, there's nothing to see here.

Just needed a convenient table for working with some home automation temperature sensors.

Conversion Formulas:
 °C  x  9/5 [1.8] + 32 = °F
(°F  -  32)  x  5/9 [~.56 or / 1.8] = °C


 °C  x  1.8 + 32 = °F
(°F  -  32)  / 1.8 = °C

Cheap Estimation Conversion:
 °C  x  2 + 30 = °F
(°F  -  30)  /  2 = °C

Quick table, adding 5 to the Celsius = adding 9 to the Fahrenheit
0=32, 5=41, 10=50, 15=59, 20=68, 25=77, 30=86, 35=95, 40=104

Other easy ones to remember:
28 C = ~ 82 F
16 C = ~ 61 F
04 C = ~ 40 F

From xkcd, just remember actual reference points, not conversions:
40 C = Really hot
37 C = I'm not sick
30 C = Warm
20 C = Nice
10 C = Cool
0 C = Cold

For scientists, to convert from Celsius to Kelvin (based on absolute zero):
°C + 273.15 = K
K - 273.15 = °C
Note: Kelvin temperature scale does not use the degree (°) symbol.

For temperature intervals rather than specific temperatures,
1 K = 1 °C = 95 °F

I remember When I was a student of matriculation,I knew all the stuff about that Celsius to Fahrenheit temperatures..I was really good at that.thank you very much for sharing.keep posting.
