A joule is the work done by applying 1 watt of power for 1 second (J = W x Time in seconds).
1 Watt is 1 Amp at 1 Volt potential (W = Amps x Volts).
1 Amp is 1 coulomb of electrons flowing in a second.
1 coulomb is 6 241 509 629 152 650 000 electrons.
Thus it would appear that there are 6,241,509,629,152,650,000 electrons in a joule, except that 1 Joule could be 2 watts for half a second (or 4 W for 0.25 seconds).
Also 1 Watt could be 2 Amps and half a volt, or .01 Amps at 100 Volts!
The question has no one answer, it has an infinity of possible answers unless more parameters are dictated.
45 volts
20 millivolts
12 volts is equal to 12000 millivolts (mV). This conversion is based on the fact that 1 volt is equivalent to 1000 millivolts.
One statvolt is about 300 volts. (299.792458)
This requires there to be two voltages, which are either equal or not equal.
1 eV is 1.6x10-19 Joules. So, 1 Joule is 1 / 1.6x10-19 eV

1 erg is equal to 0.0000001 joules.
1 JOULE= 107
One joule is 0.239 calories.
1 joule = 10 million ergs

The watt is a measurement of work done by an object at constant velocity and under constant force. 1 watt, therefore, is equal to 1 Joule per second.
12kv is equal to 12000 volt.(12*1000).
20 millivolts
There is no direct conversion between volts and joules as they are different units measuring different quantities. Volts measure electric potential difference while joules measure energy.
3 Kv = 3,000 volts.
