In the International System of **Units** (SI), **thermal conductivity** is measured in watts per meter-kelvin (W/(m\u22c5K)). ... The dimension of **thermal conductivity** is M^{1}L^{1}T^{\u2212}^{3}\u0398^{\u2212}^{1}, expressed in terms of the dimensions mass (M), length (L), time (T), and temperature (\u0398).
