In 1901, Giovanni Giorgi proposed a new system of units that would remedy this state of affairs. He noted that the mechanical practical units such as the joule and the watt are coherent not only in the QES system, but also in the meter-kilogram-second (MKS) system. It was of course known that just adopting the meter and the kilogram as base units—obtaining the three dimensional MKS system—would not solve the problem: while the watt and the joule would be coherent, this would not be so for the volt, the ampere, the ohm, and the rest of the practical units for electric and magnetic quantities (the only three-dimensional absolute system in which "all" practical units are coherent is the QES system).
