Gallon- A
unit of volume, a U.S. gallon contains 231 cubic inches, 0.133 cubic feet, or
3.785 liters (one U.S. gallon of water weighs 8.3 lbs)
Gauss- A cgs
unit of magnetic induction (or magnetic flux per unit area across an area at
right angles to the magnetic field), equal to one maxwell per square centimeter
(Cgs and mks units of magnetic induction are related by 104 gauss = 1 weber m-2
= 1 Tesla (T), where 1 weber = 1 (newton meter)/amp = 1 volt s); the induction
of the earth's magnetic field in the United States is of order 0.5 gauss, with
the magnetic field oriented about 20° from zenith (magnetic induction inside
superconducting magnets can be as high as 20 T (2 × 105 gauss), while magnetic
induction produced by the human spine is of order 15 × 10-15 T (1.5 × 10-10
gauss))
Gilbert- The
CGS unit of magnetomotive force, equal to 10/4pi = 0.795775 ampere-turns (named
for the English physicist and physician William Gilbert who published his
discoveries on magnetism in 1600)
Gram- A cgs
unit of mass; originally defined as the mass of 1 cubic centimeter of water at a
temperature of 4.5°C but now taken as the one-thousandth part of the standard
kilogram,a mass preserved by the International Bureau of Weights and Measures at
Sevrés, France.
Gray- The SI
unit of energy for the absorbed dose of radiation (one Gray is the absorption of
one Joule of radiation energy by one kilogram of matter)
