- The three really common base units ( in the S.I. system) are the metre (unit of length), the second (unit of time) and kilogram (unit of mass). With these three, we can construct a whole range of units for other quantities – e.g. the newton for force, pascal for pressure, joule for energy and so on.

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 using c as a … See more
