This conversion scales values from a larger temperature unit to a smaller one. That usually increases the numeric value when going from °C to K.
Definition: Celsius (°C) is a temperature scale where water freezes near 0 °C and boils near 100 °C at standard pressure.
History/Origin: The Celsius scale evolved from the centigrade concept and is the standard in science and most countries.
Current use: Celsius is used in weather reports, industrial control systems, and scientific measurements.
Definition: Kelvin (K) is the SI base unit of thermodynamic temperature.
History/Origin: Kelvin was established for absolute temperature measurement and is central to physics and chemistry.
Current use: Kelvin is used in scientific calculations, materials research, and color temperature specifications.
