The AMU to Joules Calculator is a scientific tool that utilizes the principle of mass-energy equivalence to convert atomic mass units (AMU) into energy expressed in joules (J). This calculator is instrumental in fields such as nuclear physics and chemistry where understanding the energy content of atomic and molecular masses is crucial.
Formula of Amu To Joules Calculator
The conversion of AMU to joules is based on the famous equation derived by Albert Einstein, E=mc^2, which explains how mass can be converted into energy:
- Convert AMU to Kilograms:
- 1 AMU = 1.66053906660 x 10^-27 kg
- Use the Mass-Energy Equivalence Formula:
- E = m * c^2
Where:
- E is the energy in joules (J)
- m is the mass in kilograms (kg)
- c is the speed of light in meters per second (m/s), approximately 3 x 10^8 m/s
The detailed conversion from AMU to energy is therefore:
E (J) = (1.66053906660 x 10^-27 kg) * (3 x 10^8 m/s)^2
Simplifying this calculation, we find:
E (J) = 1.49241808560 x 10^-10 J per AMU
Thus, to convert a given mass in AMU to energy in joules:
E (J) = mass in AMU * 1.49241808560 x 10^-10 J
This formula gives the precise energy in joules corresponding to the mass in atomic mass units, bridging atomic physics and energy quantification.
