Kelvin in Science and Engineering
Kelvin is the SI base unit for temperature, used in physics, chemistry, and engineering. Absolute zero (0 K = -273.15°C) is the coldest possible temperature. The Kelvin scale is used in gas laws, thermodynamics, and color temperature of light sources (a 6500K bulb is daylight white; 2700K is warm white).
