The SI unit of temperature is/are
kelvin
The correct answer is Kelvin (K).
While Celsius (°C) is commonly used, and Fahrenheit (°F) is used in some regions, the International System of Units (SI) officially designates the Kelvin (K) as the base unit of thermodynamic temperature. Celsius is a derived unit, defined relative to the Kelvin scale. Fahrenheit is also a derived unit, but it is not part of the SI system.
Therefore, only Kelvin is the SI unit of temperature.
