Which SI unit is used for temperature?

Explanation:
Temperature is measured in Kelvin, the SI unit for thermodynamic temperature. Kelvin is an absolute scale that starts at absolute zero—the point where particles have minimal motion. Because 0 K equals -273.15°C, using Kelvin in scientific equations keeps temperatures nonnegative and aligns directly with thermodynamic energy concepts. This makes calculations, like those in the ideal gas law, clean and consistent since temperature is tied to energy without needing offset conversions. Other options measure different quantities: mole for amount of substance, meter for length, and candela for luminous intensity.
