You can multiply the Celsius temperature by 2, subtract 10 percent, then add 32. It sounds complicated to do but it is actually easy. It would be much easier if we all were using celsius.

I have an admiration for people who know how to convert everything in their head. When it comes to that i just block and get confused. I’m sure that there are people like me out there and we all need help. The best way to convert stuff quickly is to use online converter. I’m used to the metric system and stuff like temperature in fahrenheit just sounds crazy for me. I’m immediately converting “105 f to c” to know the real temperature. The converter can also convert distance and weight which is really great. The best thing about it is that it is free, versatile and very fast.
Isn’t that the truth!
For reasonable outdoor temperatures (say, 0°C to 20°C),
To estimate the Fahrenheit value:
double the Celsius value and add thirty
(accurate to within 2°F)
To estimate the Celsius value, do the reverse caclulation:
subract thirty from the Fahrenheit value and halve the result
