When do you know to convert Celcius to Kelvin?

I always convert to Kelvin to be safe... There are many instances, such as when you calculate for entropy when you divide two temperatures, and using Celcius here will mess up your ratio and give you an incorrect answer.

You also know what to use based on the units and what you need to cancel out...

I think it is normally okay to use celcius if your data is adding or subtracting temps... as in delta T, since the difference in temperature is the same whether you subtract kelvin or celcius from each other... Hope this helps.
