The Total Binding Energy Calculator is a powerful tool that provides insight into one of the most fundamental concepts in physics—Einstein’s mass-energy equivalence equation, E = mc^2.
This equation reveals that energy (E) is directly proportional to mass (m) and the square of the speed of light (c) in a vacuum, which is approximately 931.494 MeV/u (Mega-electronvolts per atomic mass unit).

Example of Total Binding Energy Calculator
For example, if you wish to calculate the binding energy of argon-40 (40Ar), follow these steps:
- First, we need to know the mass of argon-40, which is about 39.9623831239 atomic mass units (u).
- Additionally, we need to determine the total mass of the 40 protons and neutrons in argon-40. The mass of one proton or neutron is roughly 1.007276 u.
- Calculate the mass of 40 protons and neutrons: Mass of 40 protons and neutrons = 40 * 1.007276 u = 40.29104 u
- Now, we’ll employ Einstein’s famous equation, E = mc^2, which relates mass and energy.
- Find the difference in mass between argon-40 and its protons/neutrons (Δm): Δm = (39.9623831239 u – 40.29104 u)
- Calculate the energy (binding energy) using the mass-energy equivalence principle: E = Δm * c^2
- Plug in the values: E = (-0.3286578761 u) * (931.494 MeV/u)
- Calculate the energy: E ≈ -305.79 MeV
Most Common FAQs
Binding energy represents the energy required to hold the protons and neutrons within the nucleus of an atom. It is a fundamental concept in nuclear physics and helps us understand the stability and properties of atomic nuclei.
To use the Total Binding Energy Calculator, follow the steps mentioned earlier and ensure that you have the correct values for mass (m) and the speed of light (c) in MeV/u. The calculator will provide you with the binding energy in Mega-electronvolts (MeV).
Einstein’s mass-energy equivalence equation, E = mc^2, is of paramount importance in nuclear physics because it quantifies the relationship between mass and energy. It underpins our understanding of nuclear reactions, such as those in stars and nuclear power plants.
