- The philosophy underlying natural units is to have as few base units as possible, and to define them directly through natural physical constants. The first natural units were proposed by George J. Stoney 3 (pictured).

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
