press space to insert a value for one of the units. Press K or F or C to choose one of those units of temperature. Did you realise it has the same acronym as Kentucky Fried Chicken or KFC the restaurant. If you want to be able to do it yourself follow these steps F to K= (F+459.67)/1.8 K to F= 1.8K-459.67 K to C= K-273.15 C to K= C+273.15 C to F= 1.8C+32 F to C= (F-32)/1.8
The thing in the top left corner is telling you what unit of temperature you will insert in when you press space. -40 is the only point where it's the same fahrenheit and celsius. The only point where fahrenheit and kelvin meet is 574.5875. So you might be asking at what point does celsius and kelvin meet and the answer to that question is never or I guess you could say infinite. If you make celsius 133.972222 then adding farenheit onto it will make the temperature kelvin. Make the celsius temperature -1205.75 and celsius plus kelvin will equal fahrenheit even though that temperature is impossible. Make the celsius temperature -169.527778 and farenheit plus kelvin will equal celsius. Those are just some temperature facts that one I found out on the internet the rest I used something called maths. What even is possible you ask well it's impossible to have a temperature bellow 0 kelvin.
