The SI units for the seven fundamental measurable qualities are:
A , ampere, a unit of electrical currentcd , candela, a unit of luminous intensityK , kelvin, a unit of absolute temperaturekg , kilogram, a unit of massm , meter, a unit of distancemol , mole, a unit of quantity/countings , second, a unit of time
Of course, we also have prefixes that can be appended to all of these as we wish, to express them in nicer numerical magnitudes, e.g.
pm , picometers, for atomic radiins , nanoseconds, for some first-order mean lifetimeτ≡k−1 of a fluorescent moleculemg , milligrams, for typical solid/powder drug prescriptionsmm , millimeters, for measurements using a caliper
