Page 4 - The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2 X 10"7 newton per meter of length.
Page 36 - The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 10" hertz and that has a radiant intensity in that direction of (1/683) watt per steradian...
Page 5 - The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon 12.

Page 4 - The kelvin, unit of thermodynamic temperature, is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water (13th CGPM, 1967).
Page 17 - The kilogram is the unit of mass; it is equal to the mass of the international prototype of the kilogram.
Page 24 - The metre is the length equal to 1 650 763.73 wavelengths in vacuum of the radiation corresponding to the transition between the levels 2p,0 and 5d5 of the krypton-86 atom.
Page 3 - The metre is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second.
