The equivalence is described by the famous equation:
<dl><dd></dd></dl>where E is energy, m is mass, and c is the speed of light in a vacuum. The formula is dimensionally consistent and does not depend on any specific system of measurement units. For example, in many systems of natural units, the speed (scalar) of light is set equal to 1, and the formula becomes the identity E = m; hence the term "mass–energy equivalence".[ [Wiki]
