I play on a server with people from around the world. Now that breeding is out, I no longer need to look at the temperature only for my knowledge, but also to coordinate with people to hatch our eggs. I keep running into problems with Europeans and Australians...and the rest of the world...because they use Celsius and we use Fahrenheit. Currently, my options are to either switch to Celsius (which I don't understand) or have them switch to Fahrenheit (which they don't understand). Or each time we go to tell each other a temperature, go and switch it to what ever the other person uses.
It would be amazing if there was an option to include both Celsius and Fahrenheit temperatures on the screen, rather than just one or the other.
