E = mc² Calculator — Frequently Asked Questions
Q1 What does E = mc² mean? ▾
Mass and energy are two forms of the exact same physical entity; a small amount of mass holds an enormous amount of latent energy due to the massive multiplier c² (~9 × 10¹⁶ m²/s²).
Q2 What percentage of mass is converted to energy in nuclear fission? ▾
In uranium-235 fission, only about 0.08% of mass defect is converted into energy; in matter-antimatter annihilation, 100% of mass converts into energy.
