What is a perfect physical science constant?

When I examine the NIST list of fundamental physical constants, they identify a group of constants that
they categorize as "universal".

Each of the constants have numeric values that are dependent upon SI base units or SI derived units. There
is not one unit in the list that is an actual invariable universal unit.

Are there any such physical science constants?

As Tormod has suggested, are you talking about CONSTANTS from the UNITS standpoint? It would seem that there are many "fundamental physical constants" from the standpoint that any entity that would measure it anywhere in the universe would come up with the same measurment, but would probably use a different set of symbolic units to represent it. The speed of light in a vacuum would be the speed of light in a vacuum. But they would not use meters to measure it. Such as the US might use FEET instead. Yet the speed would be the same even though it is represented by different numbers.
