Hartree energy
Definition: The Hartree energy is a unit of energy equal to approximately 4.35974 x 10^-18 joules.
Historyandorigin: It is named after Douglas Hartree and is used in atomic physics.
CurrentUse: It is used in theoretical physics and atomic-scale measurements.
funfact: The Hartree energy is approximately equal to 27.2114 electron-volts.
kilocalorie (IT) [kcal (IT)]
Definition: A kilocalorie (IT) is a unit of energy equal to 4.1868 kilojoules.
Historyandorigin: It is based on the amount of energy required to raise the temperature of one kilogram of water by one degree Celsius.
CurrentUse: It is used to measure the energy content of food.
funfact: One kilocalorie (IT) is equivalent to 1,000 small calories.

How to Convert Hartree energy to kilocalorie (IT)
1 Hartree energy = 1.041307967E-21 kilocalorie (IT) [kcal (IT)]
1 kilocalorie (IT) [kcal (IT)] = 960330690657764000000 Hartree energy
we use cross multiplication method
Hartree energy → kilocalorie (IT) [kcal (IT)]
1 → 1.041307967E-21
1.5 → ?( suppose x)
=>1.5*1.041307967E-21=1*x
by simplifying
x=1.561961951E-21
