m						@			# Length (Meter) - 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.
kg						@			# Mass (Kilogram) - The kilogram is the unit of mass; it is equal to the mass of the international prototype of the kilogram.
s						@			# Time (Seconds) - The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.
A						@			# Electrical current (Ampere) - 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 m apart in vacuum, would produce between these conductors a force equal to 2 x 10–7 newton per metre of length.
K						@			# Temperature (Kelvin) - The kelvin, unit of thermodynamic temperature, is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water.
mol						@			# Amount of substance (Mole) - 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.
cd						@			# Luminous intensity (Candela) - The candela is the luminous intensity, in a given direction, of a source that emits monochromatic radiation of frequency 540 x 1012 hertz and that has a radiant intensity in that direction of 1/683 watt per steradian.
