About the linear charge density converter

Linear charge density (λ) describes how much electric charge sits along a one-dimensional object, such as a thin wire or charged rod. The SI unit is the coulomb per meter (C/m). It appears whenever you compute the electric field around a long, charged conductor or use Gauss’s law on a line charge. Use this converter to switch between metric and imperial-length variants of charge per unit length.

Frequently asked questions

  • When is linear charge density used?

    Whenever a charge distribution is essentially one-dimensional — e.g., a thin antenna wire, a charged filament, or a transmission line.

  • What is the field around a long charged wire?

    For an infinite line, the radial electric field is E = λ / (2πε₀ r), where λ is the linear charge density.
