About Celsius and Kelvin
Celsius is the everyday metric temperature scale, with water freezing at 0° and boiling at 100° at sea level. It is used for weather, cooking and body temperature almost everywhere outside the US.
The kelvin is the SI base unit of temperature, starting at absolute zero (0 K = −273.15 °C). It is used in science and engineering, where an absolute scale matters.
The Celsius and the Kelvin are different scales, so the converter applies the exact °C → K formula — handling any offset between them — to give an accurate result every time.
