The symbol used to denote Kelvin, the unit of color temperature, is which letter?

Explanation:
The symbol used for Kelvin is K. Kelvin is the SI unit for thermodynamic temperature, and color temperature is expressed in Kelvins. When you write a color temperature, you usually see a number followed by K, like 5500 K or 3200 K. Historically you might see °K, but today the degree symbol is not used. C stands for Celsius, F for Fahrenheit, and L isn’t a standard temperature unit. So the correct symbol is K because it represents the Kelvin scale used for precise, absolute temperature measurements in color temperature.
