When did each of these words --- volt - ohm - ampere --- become used as a unit of measurement. There may be several times. The time of first useage and then the times of official definition of their values.
Here are some pieces of information:

7-13-1878 Image 95 of 287. Reference to voltameter.

The voltameter is not a volt meter, but it does show an early association of Volta's name with electrical measurement.
Unrelated to my present search but very interesting:
