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

f = c * (9/5) + 32

I mean you're not wrong Walter.

The concept is that it's a formula you can do in your head most people aren't going to spend a minute trying to work out 9/5 in their head

Nothing can go faster than the speed of light, not even fahrenheit temperature units.

Nah, the speed of light in air is faster than the speed of light in peanut butter.

Thats a very close approximate and what i use when it's numbers i have to think about for 5/9 and 9/5.
