what is the unit of Stefan constant
The SI unit of force constant is newton per meter (N/m).
The unit of the constant of proportionality in Coulomb's law is Nm²/C² or Vm.

Unit rate, slope, and rate of change are different names for the same thing. Unit rates and slopes (if they are constant) are the same thing as a constant rate of change.
Unit of Phase constant is Radians per metre .
The unit for the dielectric constant of a medium is a dimensionless quantity as it represents the ratio of the permittivity of the medium to the permittivity of a vacuum.
The SI unit of Coulomb's constant is Nm^2/C^2 (Newton meter squared per coulomb squared).
In the SI system the radiation constant (Stefan-Boltzmann constant) is measured in W/m2.K4.
