Enter two point charges and the distance between them to get the electrostatic force. Microcoulombs, nanocoulombs, millimetres and centimetres are all converted automatically.
Signs are read automatically, so you always see whether the force pulls together or pushes apart.
Enter μC, nC or full coulombs — everything is converted to base SI units internally.
Work in mm, cm or m without converting anything yourself.

Energy, gas laws and solution chemistry use the same kind of plugged-in algebra.
