I just learned the mind palace technique to memorize stuff and wanna put it to use.
For day-to-day purposes, if you are used to Fahrenheit but not Celsius or vice versa, and all you want to do is get a rough sense of how warm or cold it is outside without having to do arithmetic involving fractions in your head, then remember that there are two temperatures in Celsius that are roughly the same in Fahrenheit but with their digits transposed: 16° C ~ 61° F, and 28° C ~ 82° F. You can then roughly interpolate/extrapolate by about 2° F for every 1° C.
Also freezing is 0 in Celsius, so 32f is 0c. That one always helps me. Not as useful for converting c to f.
Bob and Doug Mackenzie thought me to roughly convert C to F by taking the temperature in Celsius, doubling it and then adding 30. It gets you in the ballpark.
Do you remember the Fibonacci sequence? You can use it to convert miles to kilometers .
2 mi ~= 3km
5mi ~= 8km
8mi ~= 13km
13mi ~= 21km
And so on.
That’s awesome thanks !
That’s brilliant.
Converting Celsius to Fahrenheit:
- multiply by 2
- remove 10%
- add 32
This is wrong? Taking 20°C as an example. Following this formula gives 48°F when it should be 68. Could you perhaps be supposed to add 32 instead of 12?
Yeah, it’s supposed to be c * 2 + 30
Nothing can go faster than the speed of light, not even fahrenheit temperature units.
