Energia Repouso E=mc²

The E=mc² Rest Energy Calculator computes the energy equivalent of a particle's rest mass, based on Einstein's equation. The formula multiplies mass (m) by the square of the speed of light (c²), illustrating the mass-energy equivalence principle. It's critical in nuclear physics, astrophysics, and particle physics studies.

To use it, input mass in kilograms. The speed of light is fixed at ~3×10⁸ m/s, but squaring it (9×10¹⁶ m²/s²) converts mass to joules. The result shows energy stored in a stationary mass, excluding motion or extreme temperatures. This calculation underpins nuclear fusion processes, like those in stars, and atomic energy concepts.

This tool is ideal for theoretical nuclear reactions, such as calculating energy released by mass conversion in reactors or stars. It should not be used for moving objects since the formula doesn't account for kinetic energy. Applications include understanding atomic bomb mechanisms and space energy calculations.

Key considerations: 1) Mass must be in kilograms (1 kg = 1000 g), 2) Energy outputs are in joules (1 J = 1 kg·m²/s²), 3) The equation applies only to rest mass, not relativistic total energy, and 4) Practical mass-to-energy conversions require specialized conditions (e.g., particle-antiparticle annihilation).
