Finding out how many parameters are necessary to explain and describe complex and various phenomena of nature has been a challenge in modern physics. This paper introduces a new formal system of units, which maintain compatibility with SI units, to express all seven SI base units by dimensionless numbers with acceptable uncertainties and to establish the number one as the fundamental parameter of everything. All seven SI base units are converted successfully into the unified dimensionless numerical values via normalization of s, c, h, k, e/me, NA, and b by unity (1). In the proposed system of units, even the unlike-dimensioned physical quantities can be convertible and hence added, subtracted, or compared to one another. It is very simple and easy to analyze and validate physical equations by substituting every unit with the corresponding number. Furthermore, it is expected to find new relationships among unlike-dimensioned physical quantities, which is extremely difficult or even impossible in SI units.
