Kelvin is the SI unit for measurement of X axis. Kelvin is a unit of measure used to measure
temperature base on the absolute scale. It is commonly used to measure the color
temperature of the light like fluorescent lamp, bulb, etc. It is also used to
indicate how noisy a certain electronic is.The symbol of Kelvin is K. here are
the conversion formula of Kelvin to F, C and Rankine
=> C = [K] – 273.15
=> R = [K] x 9/5
=> F = [K] x 9/5 – 459.67
