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 =
9⁄5 °F
