Won't your example trigger an infinite loop of celsius/fahrenheit conversions? Especially if the floating point value is slightly off.
I think your example is exactly why stuff like React won vs data-binding frameworks. With declarative programming, you just have a single source of truth that you change once (you can arbitrarily pick celsius or fahrenheit or even kelvin) and let the framework figure out what needs to be diff-ed in the derived views.
