Discover the ease of converting Hartree energy (E_h) to thermal calories (cal_th) with our user-friendly tool, designed to simplify your calculations and spark curiosity in the world of energy unit conversion.
A Hartree, symbolized as E_h, is a unit of energy used in the field of quantum chemistry and atomic physics. It is defined as the kinetic energy of an electron in an unexcited hydrogen atom. The value of one Hartree is approximately 27.211386245988 electronvolts (eV), and it serves as a natural unit of energy in the atomic scale, simplifying various calculations involving atomic-scale energies.
Definition of CalorieA calorie, often referred to as a small calorie or gram calorie (symbol: cal), is a unit of energy. Historically, it was defined as the amount of heat required to raise the temperature of one gram of water by one degree Celsius. In modern terms, one calorie is equivalent to 4.184 joules. Despite the adoption of the joule in the International System of Units (SI), the calorie is still widely used in nutrition and food energy.
