By measuring the current.
One amp is equivalent to one coulomb per second; one coulomb is defined as 6.2415 x 10^18 electrons.

eg. At one microamp, there would be a flow of 6.2415 x 10^12 electrons per second.
At one picoamp, just 6,241,500 per second!

????

Current = number of electrons per second. The coulomb unit is just what connects current (amps) to number of electrons per second.

I have provided the literal numbers in the answer.

Charles-Augustin de Coulomb invention
It is not an "invention", a machine or device, it is one of the basic numerical constants of science, named after a person as are many others.

Do you not want to use any of these because they are named after people?

Amps: André-Marie Ampère
Volts: Alessandro Giuseppe Antonio Anastasio Volta
Watts: James Watt
Ohms: Georg Ohm
Joules: James Prescott Joule

etc.

I think you need to re-state the original question so we can understand what you are really trying to do, as so far it makes no sense, sorry.

Hello
Volts is written in meter so can we write 12 Xv or Volt
after discovering Volt which is man so how to see volt
