# Some facts

• 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.

# 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.
