It is questioned why the fundamental physical constants are not fundamentally expressed mathematically.

The scheme employed here is to express all the physical constants as the factor of 2 times 3 times pi.

Pi is restricted to integer exponents, while both the 2 and the 3 may be either integer or 1/2 integer exponents.

That value is then converted to a value from 1.00000 to 9.999999 times 10 to the n. In this manner, all values can be contained and compared as to their significant digits. So, in essence here, equality refers to having equal significant digits regardless whether or not there is equality of the 10 to the E values ( as shown below ).

All physical constants have been assigned values in the form of      2 j    3 k    pi n   where,
j must be an integer or a half integer       k must be an integer or a half integer       n must be integer
