What are volts i know amps i know ohms and i know watts and what they all are a measurement for but what do volts measure if they measure voltage what is voltage.

Volt is the unit of electrical potential, which, when appied to the ends of a conductor, enables electricity to flow in this conductor. Think for example of the high tension cables which supply electric power to most communities. At one end of these cables, electric potential in thousands of volts (denoted in kilo volts or KV) may be appied, whilst at the other end, a potential of zero volt may be applied. It is important to note that it is potential difference which makes current to flow rather than the absolute potential. Thus, for example, if the potential at both ends of a conductor are both P volts, no electric current will flow, whereas if one potential is P1 whilst the other is P2, then current will flow in the direction of the lower potential.
Since you know the other units of electricity, here are some relationships between these units: V= I*R; W = V*I = I^2*R

A volt is the same as a Joule / Coulomb because it is the amount of energy available to move a coulomb of charge from one place to another place.
It is also equivalent to one watt / amp .
( an amp is a coulomb / sec and a watt is a Joule / sec)
( a Joule is a measure of energy and a coulomb is a measure of charge)
A voltage is an expression of the potential to do work (in this case to move electrical charge).

Think of Voltage as pressure or Electromotive Force or Difference of Potential.
Amperes can be compared to like the flow of water in a pipe.
Resistance is the restriction of water like a large pipe reducing to a small pipe less water flow.
Right?
Voltage is like the pressure of the water (psi etc) waiting to be released into the pipe.
Now I think you'll understand it better.
I hope so.

Voltage is potential, if you liken an electric circuit to water in a pipe then voltage is like pressure current is like flow rate resistance is not so easy but it's like pipe diameter

Think of volts as pressure, and amperes as volume, of electrons flowing as a fluid.
You may think of ohms as friction.
Be careful not to carry the analogy too far, but it helps at this level.

volt = ohm * amp
volt = watt / amp

voltage is called potiontial difference.like natural energy sources like,water flows from up to down,the flow of ampere (i.e. current)requires up and down.The voltage is doing the updowns for the electrc flow.It,s also the unit for measuring pd.

Volt is the difference of electrical potential of two points.when we say this point is 220 volt, it means, that point is 220 volt higher in electrical potential than the specific point.
