; The physical constants for c (speed of light in meters per second), 
;  e (charge of an electron in Coulombs), 
;  h (Plank's constant in kilogram meters squared per second),
;  k (Boltzman's constant in kilogram meters squared per second squared Kelvin),
;  m (rest mass of an electron in kilograms), and
;  s (price of gold in 1990 in US dollars per kilogram)
