Multiples of R to joules per mole per kelvin
Type a value in R to get it in J/(mol·K) instantly.
831.4J/(mol·K)
That's 2.8× as high as a large molecule — nothing on our list beats it. That is about 100 times the gas constant R.
Convert the other way: J/(mol·K) to R
What it means
How much is that?
The same units serve molar entropy and molar heat capacity, because the two have identical dimensions.
The math
How to convert R to J/(mol·K)
To convert multiples of R to joules per mole per kelvin, multiply by 8.31446.
Example: 100 R × 8.31446 = 831.446 J/(mol·K).
In the other direction, 1 J/(mol·K) = 0.120272 R.
