### Temperature in PV=nRT

What is the unit we should be using for temperature in PV=nRT?

Temperature is in Kelvin (K)

We have to use Kelvin temperature since in this formula T could be at the denominator. If we were using Celsius unit, then we would have had zero at the denominator at some point. Because a zero denominator does not give us a solution, we use kelvin. when kelvin is zero that suggests we have an absolute zero temperature and there would be no gas law.

If you're given the temperature in celsius, you can easily convert it to Kelvin by adding 273.15

The unit we use for temperature in this equation is Kelvin (K). If the temperature is given in Celsius, add 273.15 to convert to Kelvin.

Just adding to that, temperature is the most determining factor of the characteristic of the gas.

Temperature has to be in Kelvin always. Unlike P or V in the PV=nRT equation, where P can be in atm/Pa/etc or V can be L/m^3/etc or they can both be combined into eV/J/cal, T always has to remain in K (similar to n, which always has to remain in mol).

### Re: Temperature in PV=nRT

The unit for T in this case is always in Kelvin (K)

Kelvin is the SI unit for temperature.
