conversion of entropy

Are two units kj/kg.k and kj/kg.c equal?(about unit of entropy)
I got in trouble to calculate the entropy unit?

Please help.

Always use Kelvin for temperature units because Celsius is not an SI unit. Celsius should be seldom used unless you're quoting a temperature in Celsius (like T= 25 $\displaystyle ^o$C)

Without any doubt entropy is kJ/K. Note entropy is an extensive quantity.

The units you wrote do not correspond to entropy, but to specific entropy with units kJ/kg.K.

As advised above one should always use the Kelvin units for temperature. When units are in denominator we indeed are using corresponding delta value of unit magnitude on a given scale. This fact needs to be always kept in mind.
