Some facts

  • The electric dipole moment for a system consisting of two or more point charges is defined as the below sum:
    p=i=1...nqiri\overrightarrow{p} = \sum_{i=1...n}{q_i \overrightarrow{r_i}}
    • p\overrightarrow{p} - electric dipole moment of the whole system,
    • ri\overrightarrow{r_i} - a vector pointing to the i-th electric charge,
    • qiq_i - value of i-th charge,
    • nn - 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:
    i=1...nqi=0\sum_{i=1...n}{q_i} = 0
  • The unit of electric dipole moment in SI system is coulomb times meter:
    CmC \cdot m
  • Another unit, used mainly by chemists and atomic physics, is 1 debye:
    1D=3,335641030Cm1 D = 3,33564 \cdot 10^{-30} C \cdot m
  • If the system with the dipole moment p\overrightarrow{p} is introduced into the external electric field E\overrightarrow{E}, then the moment of force will act on it is:
    M=p×E\overrightarrow{M} = \overrightarrow{p} \times \overrightarrow{E}
  • Molecules with non-zero dipole moment are called polar. An example of such a molecule is water (H2O 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 (CCl4 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.
    • 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.
