Effortlessly convert Hartree Energy to Kilocalorie IT with our precise Eh to kcal tool. Designed by Newtum, it sparks curiosity and simplifies complex calculations for enthusiasts and professionals alike.
The Hartree, symbolized as Eh, is a unit of energy named after the British physicist Douglas Hartree. It is used in the field of atomic physics and quantum chemistry. The Hartree is specifically the measure of energy in the atomic unit system, equivalent to the energy of a single electron in the ground state of a hydrogen atom. Its value is approximately 4.359744650×10^-18 joules or 27.21138602 electronvolts.
Definition of KilocalorieA Kilocalorie, often denoted as kcal, is a unit of energy commonly used in measuring the calorific, heating, or metabolic value of foods. One Kilocalorie is equivalent to the energy needed to raise the temperature of one kilogram of water by one degree Celsius. In dietary terms, the Kilocalorie is used to quantify the amount of energy that food provides to the body. Its scientific equivalent is 1,000 calories, with the calorie being a smaller unit of energy.
