The International System of units used nowadays in most of the word experienced a turning point in the first half of the XX century with the introduction of the ampere (A) as a fourth unit in addition to the original length (M – meter), mass (K – kilogram) and time (S – second), hence turning from a MKS to a MKSA system. This addition was a non-trivial and lengthy process mainly carried on by the Italian engineer Giovanni Giorgi. This contribution retraces this revolution in the measurement system.

Abstract
The International System of units used nowadays in most of the word experienced a turning point in the first half of the XX century with the introduction of the ampere (A) as a fourth unit in addition to the original length (M – meter), mass (K – kilogram) and time (S – second), hence turning from a MKS to a MKSA system. This addition was a non-trivial and lengthy process mainly carried on by the Italian engineer Giovanni Giorgi. This contribution retraces this revolution in the measurement system.
