What is unit and dimension of thermal conductivity?

Solution

$Rate space of space change space of space heat space is space given space by comma space space space space space space space space space space space space space space space space space space space space space dQ over dT equals straight K straight A over straight ell straight theta space therefore space space space space Thermal space conductivity comma space straight K equals dQ over dt straight ell over Aθ$
S.I. unit of thermal conductivity is Watt/m/K or J/s/m/K.

CGS unit of K is cal/cm/sec/K or ergs/cm/sec/K.

Dimensional formula of thermal conductivity is [M¹L¹T^–3K^–1]
