Unit of Universal Gas Constant

Si Unit of Universal Gas Constant is J/mol K (Joles per mole Kelvin), but other than this there are some more units for Universal Gas Constant that are listed as follows:

Liters·atmospheres per mole per Kelvin (L·atm/mol·K)
Cubic meters·Pascals per mole per Kelvin (m³·Pa/mol·K)
Calories per mole per Kelvin (cal/mol·K)
Ergs per mole per Kelvin (erg/mol·K)

Value of Universal Gas Constant in Different Units

Inverse uses of the gas constant can be found in many academic fields. It is expressed in multiple units as a result. Here is a list of some gas constant values in various units:

Unit	Value of R
Joules per mole per Kelvin (J/mol·K)	8.314462618 J/mol·K
Liters·atmospheres per mole per Kelvin (L·atm/mol·K)	0.08205736608096 L·atm/mol·K
Cubic meters·Pascals per mole per Kelvin (m³·Pa/mol·K)	8.314462618 m³·Pa/mol·K (equivalent to J/mol·K)
Calories per mole per Kelvin (cal/mol·K)	1.987 cal/mol·K
Ergs per mole per Kelvin (erg/mol·K)	8.314462618 x 10^7 erg/mol·K

Value of Universal Gas Constant at ATM

The R constant for atm in the US Standard Atmosphere is provided as

R is equal to 8.31432×103 N⋅m⋅kmol⁻¹⋅K⁻¹

Universal Gas Constant

Gas Constant or Universal Gas Constant is a physical constant, represented by the letter R, and is expressed in terms of energy units per mole of temperature increment. The value of the gas constant is the same as that of the Boltzmann constant, but it is expressed as the pressure-volume product rather than the energy per particle increment of temperature. In this article, we will look into what is Universal gas constant, it’s value and uses, etc.
