At the risk of sounding silly, you may need to be able to convert temperature from Celcius to Farenheit and/or back again to know what your field conditions are in order to make informed decisions about battery life, flying behavior, time, etc.

To convert C to F: C(1.8) + 32 = F

Example: Temp in Celcius is 8 degrees. 8(1.8) + 32 = 46.4F

To convert F to C: (F-32)/1.8 = C

Example: Temp in Farenheit is 30 degrees. (30-32)/1.8 = -3.6C

I fly in near Phoenix, AZ where it's mostly sunny all year, but I will be flying in Flagstaff next week (snowy conditions). Hopefully this is helpful to someone. You may not always be able to plug a number into a conversion table while in the field.

Happy Holidays and safe flying!

How does knowing how to convert temp help?  If you know the temperature, why do you need to convert it so you can be informed to fly?    You sound silly.

Battery operating ranges are given in C. Since we are given temps in F in the U.S., it seems some may benefit from this. If you don't need it, great.

Nice sharing !  Some guys may find it useful ! Merry christmas !
