Convert Femtocoulombs per cubic metre to Gigacoulombs per cubic metre
Convert Femtocoulombs per cubic metre (fC/m³) to Gigacoulombs per cubic metre (GC/m³) instantly and accurately.
Conversion Formula
GC/m³ = fC/m³ × 1.000000000e-24
About Femtocoulombs per cubic metre
The femtocoulomb per cubic metre (fC/m³) equals 10⁻¹⁵ C/m³, the scale for charge density in the interstellar medium. The diffuse interstellar medium has electron density ~3×10⁴ /m³, giving charge density ≈5 fC/m³; radiation belt proton charge density in the inner Van Allen belt is in the fC/m³ range. 1 fC/m³ = 10⁻¹⁵ C/m³ = 10⁻³ pC/m³.
About Gigacoulombs per cubic metre
The gigacoulomb per cubic metre (GC/m³) equals 10⁹ C/m³, the natural scale for free-electron charge density in metals. Copper has ~8.5×10²⁸ free electrons/m³, giving total free-charge density ≈13.6 GC/m³; gold is ≈9.4 GC/m³; this scale is also used in extreme fusion plasma models at densities above 10²⁸ /m³. 1 GC/m³ = 10⁹ C/m³ = 10³ MC/m³.
