- The
**electric dipole moment**for a system consisting of two or more**point charges**is defined as the below sum:

$\overrightarrow{p} = \sum_{i=1...n}{q_i \overrightarrow{r_i}}$where:

**$\overrightarrow{p}$**- electric dipole moment of the whole system,

**$\overrightarrow{r_i}$**- a vector pointing to the i-th electric charge,

**$q_i$**- value of i-th charge,

**$n$**- number of charges in the system.

- Dipole moment is a
**vector**. - The dipole moment makes sense for
**neutral systems**, i.e. where the sum of all charges is zero:

$\sum_{i=1...n}{q_i} = 0$ - The unit of electric dipole moment in SI system is
**coulomb times meter**:

$C \cdot m$ - Another unit, used mainly by chemists and atomic physics, is
**1 debye**:

$1 D = 3,33564 \cdot 10^{-30} C \cdot m$ - If the system with the dipole moment $\overrightarrow{p}$ is introduced into the external electric field $\overrightarrow{E}$, then the moment of force will act on it is:

$\overrightarrow{M} = \overrightarrow{p} \times \overrightarrow{E}$ - Molecules with
**non-zero dipole moment**are called**polar**. An example of such a molecule is water ($H_2O$). - If the electric charges in the system are
**evenly distributed**, then the dipole moment of such a system is zero. Examples of such systems are**chemical molecules with a symmetrical structure**such as carbon tetrachloride ($CCl_4$). Such molecules are called**apolar**or**non-polar**.

**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.
