What is the si unit of temperature?

Verified Answer

The SI unit of temperature is the kelvin (K). It is the standard unit used worldwide in science and scientific calculations.

The Kelvin scale begins at absolute zero (0 K), the lowest possible temperature at which particles have minimum thermal energy. Unlike the Celsius scale, the Kelvin scale does not use the degree symbol (°).

For reference:

  • 0°C = 273.15 K

  • 100°C = 373.15 K

Kelvin is widely used in physics, chemistry, and other scientific fields for accurate temperature measurements.
