How to use the Coulomb’s Law Calculator
- Fill in the values you know. Fields already contain typical example values that you can overwrite.
- Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
- Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
- A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.
If a value is missing or does not make sense, the field shows a short message explaining what to fix.
Formulas used
This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:
force = Coulombs_constant / relative_permittivity × charge1 × charge2 /distance^2
Coulombs_constant = 1 / 4 / pi / vacuum_permittivity
force_equal = Coulombs_constant / relative_permittivity × charge × charge /distance^2

Frequently asked questions
What is Coulomb’s Law?
Coulomb’s Law describes the force between two charged objects. It states that the force (F) between two charges (q1 and q2) is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance (r) between them. Mathematically, it’s expressed as F = k * (|q1 * q2|) / r², where k is Coulomb’s constant.
How does the Coulomb’s Law Calculator work?
The Coulomb’s Law Calculator effortlessly computes the electrostatic force between two charges based on their magnitudes and the distance separating them. Simply input the values for the charges and the separation distance, and the calculator uses the formula to deliver the result quickly.
What units are typically used in Coulomb’s Law calculations?
In Coulomb’s Law calculations, the standard units are:
- Charge: Coulombs (C)
- Distance: Meters (m)
- Force: Newtons (N)
