Standard units of measurement are established by the official organization that is tasked with the standardization of international weights and measurements, ensuring that the entire world uses the same standards of weight and measurement.

Thank you. A "volt" is a unit of electric potential, also known as electromotive force, and represents "the potential difference between two points of a conducting wire carrying a constant current of 1 ampere, when the power dissipated between these points is equal to 1 watt. The characteristics of voltage are like that of water flowing through pipes. This is known as the "water-flow analogy", which is sometimes used to explain electric circuits by comparing them with a closed system of water-filled pipes, or "water circuit", that is pressurized by a pump.
Refer to the image below to visualize how voltage and electric current works Current I is a rate of flow and is measured in amps A. Ohms R is a measure of resistance and is analogous to the water pipe size.
Volt measure the work done by an electric charge to move from one end to another. It is the unit of the potential difference, electric potential and electromotive force. The volt is represented by the symbol V.
Micro-volt, millivolt, kilovolt, and mega volt are the subunit of the volts. One volt is equal to the work done by one joule to charge the body at one coulomb. The ampere is the SI unit of electric current. As you know there should be sufficient pressure in the large pipe to lift water up the smaller pipe.
Higher the pressure in the large pipe more water flows out through the smaller pipe. In addition to, the diameter of smaller pipes also determines the water flow. Hope this analogy has made volts vs amps more clear to you. Volts represent the measure of potential difference between any two points in an electric field whereas ampere is the rate of current flow in a conductor or a circuit. Hope that the above explanations and analogy has helped you understand the difference between volts and amps or ampere.
