Not sure of the original source of this data, but looks reasonable.
Pretty sure the columns are Kelvin, Centigrade and Fahrenheit.
I suggest a reasonable range would be 500C to 600C, more towards 600C than 500C.
i think you mean, F, K, C for the order of the scales. fahrenheit is the largest number, and kelvin is 270 difference from celcius.
so, yeah, how quickly does yellow hot lead cool in freefall on a summery day?
