Now you’ll know how to do it !

Oh….Wait. It’s not that simple after all. Per metric-conversions.org:
“Common conversions from Celsius to Fahrenheit
- 25°C= 77°F
- 30°C= 86°F
- 33°C= 91.4°F
- 35°C= 95°F
- 40°C= 104°F
- 180°C= 356°F
Why is converting Celsius to Fahrenheit so difficult?
Because both Celsius and Fahrenheit scales are offset– ie neither are defined as starting at zero. On top of that, for every additional unit of heat energy the Celsius and Fahrenheit scales add a different additional value. Because of this setup, it’s impossible to say that doubling the °C or °F value doubles the amount of heat energy, so it’s difficult to get an intuitive grasp of how much energy 1 degree Fahrenheit or Celsius actually is.”
Well, looking at the above sample conversions, we’re pretty good using 1000LifeHacks formula. It may be off a hair or two, but should be close enough when speaking about the weather, but not rocket science !
The rule we were always taught was that you take fahrenheit divide it in half and subtract 15. Of course that’s just a guestimate…
