[Help-gsl] Physical constants

[Sebastien Maret]

I am a bit confused by the different headers in the GSL that define
the physical constants. The reference manual only mention
gsl_const_mksa.h and gsl_const_cgsm.h. The former defines the constant
in MKS units and the second one in CGS. But the source distribution
also have gsl_const_mks.h and gsl_const_cgs.h. What are those?

Is there any reason why the SI system is called MKSA in the reference
manual and not simply MKS? Does the A stands for ampere? What about
the M in CGSM?
