The only difference between Kelvin and Celsius is where the 0's at. The magnitue of each degree is the same, everything. It's just that when dealing with common day temperatures Celsius make's more sense to us with how our mind works. Zero is a tangible number to work out from. Which scientists do when using Kelvin. It doesn't do it when you work in a kitchen, or look out side to see if the water is freezing.
So if you want Kelvin you should be just bloody fine with Celsius since it uses the same magnitude of scale, only have a different zero. They just have different practicalities.
