<prompt> Tekanyo ea mocheso e sebelisoang tsamaisong ea SI ke eng?nan  <response>: Instruction in English: What is the unit of temperature used in the SI system? . Response in English: The unit of temperature used in the International System of Units SI is the kelvin K. It is the primary unit of temperature measurement in the physical sciences, and is one of the seven base units in the SI system. The kelvin is defined by setting the numerical value of the Boltzmann constant to 1.380649 × 1023 joule per kelvin JK, effectively defining the kelvin in terms of the fundamental physical constant k. . Response in Sesotho: Karolo ea mocheso e sebelisoang ho International System of Units SI ke kelvin K. Ke karolo ea mantlha ea tekanyo ea mocheso ho mahlale a fisiks, me ke e ngoe ea likarolo tse supileng tsa sistimi ea SI. Kelvin e hlalosoa ka ho beha boleng ba linomoro tsa kamehla ea Boltzmann ho 1.380649 × 1023 joule per kelvin JK, e hlalosa hantle kelvin ho latela sebopeho sa mele sa mantlha sa k.
