    About degree Celsius

    Degree Celsius (°C) — The Celsius scale sets 0 °C near the freezing point of water and 100 °C near boiling at standard pressure.

    Common uses: Celsius is used in most countries for weather, cooking, science, medicine, and everyday temperature readings.

    About kelvins

    Kelvin (K) — Kelvin is the SI base unit of thermodynamic temperature. It is an absolute scale where 0 K is absolute zero, equal to -273.15 °C.

    Common uses: Kelvin is used in science, physics, chemistry, engineering, astronomy, thermodynamics, and lighting color temperature.
