On the wiki page theres a table of values for different units. I don't understand what they mean though. For example, the value for litre torr per mol kelvin is 62.36367(11). What does the (11) mean? In this tutorial:
http://www.mikeblaber.org/oldwine/chm1045/notes/Gases/Density/Gases05.htm
they use 6236 as the value for that gas constant in those units. I'm lost.

you typed (omitting the decimal point)
6236
The mikeblaber.org page is different from what you have typed -- it is
62.36 L torr/mol K
Do you see the similarity to
litre torr per mol kelvin is 62.36367(11)

The various units are measured in absolute values. So, for instance.  you would use K (kelvin) for temperature and not C (centigrade).

There are the only two R values you need:
R = 8.314472 J mol^-1 K^-1
Note the units contain J, hence use for energy calculations  -nFE° = ΔG = ΔH – TΔS = -RTln K; 
rate = Aexp-(Ea/RT) because your energies are in J mol^-1 convert kJ→J, g→mol;  and T in K.
R = 0.0820574 L atm mol^-1
For the Ideal Gas Eqn  PV = nRT
Note units of L atm mol^-1
So get your Pressure into atm (eg ÷ torr by 760) and V in L (÷ mL by 1000) K;  g→mol;
once again T in K = T°C + 273.2 n in mol 
The (11) is the standard deviation in the last two numbers; it gives an indication of the experimental
uncertainty in R.
