SUMMARY

The discussion focuses on calculating the energy released from a mass defect of 1 atomic mass unit (1u) using both kilograms and MeV/c² as units. It is established that 1u equals 931.5 MeV/c² and 1.67 x 10-27 kg. The confusion arises when users attempt to apply Einstein's equation E=mc² with these units, leading to mismatched calculations. The issue was resolved by demonstrating the energy calculation using both units, clarifying the conversion process.

PREREQUISITES
  • Understanding of Einstein's equation E=mc²
  • Knowledge of atomic mass units (u) and their conversions
  • Familiarity with energy units such as MeV and joules
  • Basic skills in performing unit conversions
NEXT STEPS
  • Study the conversion between atomic mass units and energy units, specifically MeV/c²
  • Learn how to apply Einstein's equation E=mc² in practical scenarios
  • Explore the concept of mass defect in nuclear physics
  • Investigate the implications of energy-mass equivalence in particle physics
USEFUL FOR

Students and professionals in physics, particularly those focused on nuclear physics, energy calculations, and unit conversions. This discussion is beneficial for anyone seeking to understand the relationship between mass and energy in theoretical and practical applications.

So 1u = 931.5Mev/c2 = 1.67 10_27 kg . the thing is when i calculate E=mC2 with both units the calculations don't match . i can't understand why .

Thank you for the attention sir . unfortunately i am using my phone to type so i cannot write all the calculation . can you please write the Energy released out of a mass defect of 1u by using Kg first then MeV /C2 as the unit of mass ? That can solve my problem
 
The problem is solved . thank you

Please note that this is usually not an acceptable excuse to not lay out the full and complete post. It is why the PF Rules also prohibit text-speak.
