About this calculator
The statcoulomb (esu) is the unit of electric charge in the CGS-Gaussian system, defined so that two equal charges of 1 statC placed 1 cm apart in vacuum repel each other with a force of exactly 1 dyne — it converts to the SI coulomb at 1 statC ≈ 3.33564×10⁻¹⁰ C, a factor directly tied to the speed of light (1 statC = 1/(2.99792458×10⁹) C).
Theoretical and astrophysicists still use Gaussian/CGS units, following the convention of classic textbooks like Jackson's Classical Electrodynamics, because Maxwell's equations take a more symmetric form without ε₀ and μ₀, so converting statcoulombs to coulombs is a routine step whenever their results need to interface with SI-based engineering or experimental data.
