Some facts#

The electric potential in point is the ratio of the amount of work (done by electrical force) that should be done in order to move the electric charge from this point to the infinity to the value of this charge:

$\varphi(x_0) = \dfrac{W_{x_0 \rightarrow \infty}}{q}$
where:
- $\varphi(x_0)$ - electric potential at $x_0$ ,
- $W_{x_0 \rightarrow \infty}$ - work to be done to move the charge q from point $x_0$ to infinity,
- $q$ - charge value.
The electrical voltage is the electrical potential difference measured in two selected points:

$U_{AB} = \varphi_B - \varphi_A$
where:
- $U_{AB}$ - electric voltage beetwen points A and B,
- $\varphi_A$ - electric potential in point A,
- $\varphi_B$ - electric potential in point B.
ⓘ Remember: Electric voltage always applies to two points. When we talk briefly about voltage, in practice we have in mind the voltage between the points (or in other words: the voltage in relation to the reference point). In the case of electronic circuits, the reference point is usually the so-called ground, against which all voltages (potentials) in the circuit are measured.
The basic unit of the electrical voltage is one volt (1V).
The electrical voltage is usually denoted with a capital letter U or V.
The device for measuring the voltage is voltmeter.

How to convert#

Enter the number to field "value" - enter the NUMBER only, no other words, symbols or unit names. You can use dot (.) or comma (,) to enter fractions.
Examples:
- 1000000
- 123,23
- 999.99999
Find and select your starting unit in field "unit". Some unit calculators have huge number of different units to select from - it's just how complicated our world is...
And... you got the result in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you're looking for.
