conversion/relationship: Thermal conductivity (k) to Newtons Law of Cooling (k)

Is there a conversion factor from the specific substance (k) value in Q/t = -kA (T2-T1)/L
thermal conductivity, in units, cal/sec/m Kelvin.
To the (k) value in Newtons Law of Cooling dT/dt = -k (T object - T surroundings ) or can the (k) in the
cooling solution, T(t) = T surr + (T obj - T surr ) e^-kt
in units 1/sec only be obtained by taking temp at t0,t1.t2 and solving.
