Dipole Moment Calculator
⚛ Atomic & Quantum. Use the Dipole moment formula to find dipole moment μ, charge, separation: pick the value you want, type the others, and the answer updates as you go.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Dipole moment μ | C·m |
| Charge | C |
| Separation | m |
Worked example
Find the dipole moment μ when Charge = 1.602 × 10⁻¹⁹ C, Separation = 1 × 10⁻¹⁰ m.
Using μ = q × d: Dipole moment μ = 1.6 × 10⁻²⁹ C·m.
Frequently asked questions
What is the formula for Dipole moment?
μ = q × d.
What do the letters stand for, and what units are used?
Dipole moment μ in C·m, Charge in C, Separation in m.
How do you calculate dipole moment μ?
Put the values into μ = q × d. For example, with Charge = 1.602 × 10⁻¹⁹ C, Separation = 1 × 10⁻¹⁰ m, dipole moment μ = 1.6 × 10⁻²⁹ C·m.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (dipole moment μ, charge, separation) and fill in the others: it rearranges the formula for you.
