Millijoule To Hartree Converter

Seamlessly Convert mJ to E_h with Precision

Discover the simplicity of converting millijoules to hartrees using our mJ to E_h tool. Curated by Newtum, this is the go-to resource for quick and accurate energy conversions.

What are Millijoule and Hartree

A millijoule (mJ) is a unit of energy equal to one-thousandth of a joule, the standard unit of energy in the International System of Units (SI). It is a small unit of energy used in various scientific and technical fields, often for measuring the amount of work done or heat produced in particular reactions or processes.

The hartree (E_h) is a unit of energy specifically used in the field of atomic physics. It is named after the physicist Douglas Hartree and is equivalent to the energy of the electron's attraction to the nucleus in the hydrogen atom in its ground state. The hartree is a fundamental unit in quantum chemistry calculations.

History of Millijoule and Hartree

A brief history of the Millijoule to Hartree Energy Converter traces back to the development of energy measurement standards. The converter is a tool stemming from the need to bridge classical and quantum measurement units, particularly useful in physics and chemistry where precise energy conversions between different scales, like the millijoule (a SI unit) and the hartree (a quantum physics unit), are essential.
