1 kilocalorie [I.T.] = 9.603307 × 10²⁰ hartree.
1 hartree = 1.041308 × 10⁻²¹ kilocalorie [I.T.].
Multiply the value in kilocalorie [I.T.] by 9.603307 × 10²⁰ to get the result in hartree. Example: 5 kcal × 9.603307 × 10²⁰ = 4.801653 × 10²¹ Eh.
Kilocalorie [I.T.] (kcal) is a unit of energy. "I.T." stands for the International Table definition.
1 kilocalorie [I.T.] = 4,186.8 joule (J)
1 kilocalorie [I.T.] = 1,000 calorie [I.T.] (cal)
1 joule = 0.0002388459 kilocalorie [I.T.]
The SI prefix kilo- stands for 1,000, so 1 kilocalorie [I.T.] = 1,000 calorie [I.T.].
