- Natural units are a system of units used principally in particle physics1. In natural units, all quantities that have dimensions involving length, mass, and time are given dimensions of a power of energy (usually expressed in electronvolts)1. The philosophy underlying natural units is to have as few base units as possible, and to define them directly through natural physical constants2. With the three common base units of length, time, and mass, we can construct a whole range of units for other quantities3.Learn more:✕This summary was generated using AI based on multiple online sources.

Natural units - Wikipedia
In physics, natural unit systems are measurement systems for which selected physical constants have been set to 1 through nondimensionalization of physical units. For example, the speed of light c may be set to 1, and it may then be omitted, equating mass and energy directly E = m rather than … See more
