How do you convert J to kcal mol?

In SI units, one kilocalorie per mole is equal to 4.184 kilojoules per mole, or 6.9477×10−21 joules per molecule, or 0.043 eV per molecule. At room temperature (25 °C, 77 °F, or 298.15 K) it is equal to 1.688 units in the kT term of Boltzmann’s equation.

Calories Joules
10 cal 41.84 J
11 cal 46.02 J
12 cal 50.21 J
13 cal 54.39 J

How do you convert joules to joules per mole?

  1. The joule per mole (symbol: J·mol−1 or J/mol) is an SI derived unit of energy per amount of material.
  2. Since 1 mole = 6.02214076×1023 particles (atoms, molecules, ions etc.), 1 joule per mole is equal to 1 joule divided by 6.02214076×1023 particles, 1.66054×10−24 joule per particle.
