Answer 1

My dear friend I'm back to answer one of the most difficult answers again but for helping me out i would please everybody to set the question with detail and carefully so i get the right meaning.

If i understood correct you want the scientific symbol which symbolizes a standard.

Actually the right name for those symbols in the scientific world are called

constants and they are about 600 something...

To give an example what you need to know:

For example G it's the acceleration of free fall on earth...

London Equator and the poles have a different standard number.

Answer 2

The term that describes a standard is "benchmark." A benchmark is a point of reference against which things can be compared or evaluated for quality, performance, or value.
