The variation in thermal conductivity of a material with temperature in the temperature range of interest can be approximated as a linear function as:
k(T)=k'(1+βT)
Where β is called Temperature coefficient of thermal conductivity. Thus, its unit is K−1K−1and its dimension is K−1K−1.
Since, it's value depends on temperature range, it is not possible to give it's value explicitly

________
conductivity is measured in watts per meter-kelvin (W/(m⋅K)).
The dimension of thermal conductivity is M1L1T−3Θ−1, expressed in terms of the dimensions mass (M), length (L), time (T), and temperature (Θ).
