The kelvin, symbol K, is the SI base unit of temperature, named after the Belfast-born and University of Glasgow based engineer and physicist William Thomson, 1st Baron Kelvin. The Kelvin scale is an absolute thermodynamic temperature scale, meaning it uses absolute zero as its null point. It is often used to measure the colour temperature of light sources, and is used in photography as a temperature unit to set white balance.
