This is within the software, when you look at the performance graphs and the overlay on your screen. Everything is Celsius
That's because in computers, safe and dangerous temperature ranges are defined in centigrade, so there is absolutely no reason to use Fahrenheit.
Maybe where you live but I see no need to use the Celsius scale, here in America, where no one here uses it except as a number displayed right along side the Fahrenheit numbers. People use the scale they are accustomed, to determine (mostly), if something is normal or out of spec/scale and if so, by how much. Assuming that the scale YOU use means MORE than what someone in another part of the world uses is both useless and arrogant. Almost all software that assumes Celsius is the default scale to use, at least, gives us the ability to change it to one we are more comfortable/familiar with. Leaving out that feature alienates your audience and is like writing an owner's or user's manual and failing to include translations to the most widely used languages.
