## 10. gslconst: The GSL Constants Module

The GSL constants module `gslconst` defines about 200 physical constants such as the speed of light (`CONST_MKSA_SPEED_OF_LIGHT`) and Boltzmann's constant (`CONST_MKSA_BOLTZMANN`). In addition to providing values in the MKSA (meters, kilograms, seconds, amperes) system, the module also includes CGSM (centimeters, grams, seconds, gauss) versions, e.g., `CONST_CGSM_SPEED_OF_LIGHT`.
