SI unit of temperature is

  • A.Kelvin
  • B.Celsius
  • C.Fahrenheit
  • D.Joule

Answer: A

The SI unit of temperature is the kelvin.

It is one of the seven base units, and the scale starts at absolute zero, so no negative values occur. A kelvin and a degree Celsius are the same size, and \(T(\mathrm{K}) = t(^\circ\mathrm{C}) + 273.15\).
