/*! Physical Constants
This chapter describes macros for the values of physical constants, such as the speed of light, c, and gravitational constant, G. The
values are available in different unit systems, including the standard MKSA system (meters, kilograms, seconds, amperes) and the CGSM
system (centimeters, grams, seconds, gauss), which is commonly used in Astronomy.
## References and Further Reading

information on the values of physical constants is also available from the NIST website.
