CGS system (NASA SP-7, 1965) A system of units based on the centimeter, the gram, and the second. Cha, Cham (NASA SP-7, 1965) International Astronomical Union abbreviations for Chamaeleon. See constellation.
Einstein used the CGS system of units (centimeters, grams, seconds, dynes, and ergs), but the formula is independent of the system of units. In natural units, the speed of light is defined to equal 1, and the formula expresses an identity: E = m.
physical system = cgs system. physiological acceleration The acceleration experienced by a human or an animal test subject in an accelerating vehicle. See table XI.
The gauss is a unit of magnetic induction (denoted B) in the cgs system (centimeter-gram-second). A changing magnetic field produces an electric current - this is called magnetic induction.
