Convert Kilovolt-metres to Femtovolt-metres
Convert Kilovolt-metres (kV·m) to Femtovolt-metres (fV·m) instantly and accurately.
Conversion Formula
fV·m = kV·m × 1.000000000e+18
About Kilovolt-metres
The kilovolt-metre (kV·m) equals 10³ V·m. By Gauss's law a surface enclosing 1 µC has total flux Q/ε₀ ≈ 113 kV·m; flux through a 10 m² cross-section of a 100 V/m atmospheric field region is 1 kV·m; flux integrals in high-voltage substation insulator analysis are in the kV·m range. 1 kV·m = 10³ V·m.
About Femtovolt-metres
The femtovolt-metre (fV·m) equals 10⁻¹⁵ V·m, the smallest practical scale for electric flux. Shot noise-limited flux measurements in single-electron transistors and nanoscale sensors operate in the fV·m range; flux through sub-micron apertures exposed to extremely weak quasi-static fields spans fV·m to pV·m. 1 fV·m = 10⁻¹⁵ V·m = 10⁻³ pV·m.
