'Electricity' is not a quantity, so cannot be measured and, therefore, has no unit of measurement. It is the name of a field of study, just like 'chemistry', etc.
A 'unit' of electrical energy is short for 'Board of Trade Unit' (a former government organisation that, at one time, set energy prices in the UK), and is exactly equivalent to a kilowatt hour, which is defined as the amount of energy consumed, over a period of one hour, at a rate of one kilowatt. A unit or kilowatt hour is equal to 3.6 million joules (a joule being the SI unit for energy), and normally costs around £0.15 to buy.
if i got your question right, in physics the chapter on practical electricity, 1 kWh is equals to 1 unit

A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWH) of electricity.
The unit of energy in an electricity bill is a kilowatt-hour, also known as a Unit. To calculate the energy in units, multiply the power in kilowatts by the time in hours.

That number is called "i", the imaginary unit. The name "imaginary" is for historical reasons; these numbers have many practical applications, for example in electricity.
Electricity
At present, it is not practical.
Not to any practical extent
What is practical is a relative question. The unit for electric cars and biology may be Kilo Joules and ev, electron volts.

The answer is no. Although it could be possible, it is not practical.
The unit of measure for amount of electricity is voltage.
watts
ohms
