Convert Picofarads per metre to Nanofarads per centimetre
Convert Picofarads per metre (pF/m) to Nanofarads per centimetre (nF/cm) instantly and accurately.
Conversion Formula
nF/cm = pF/m × 1.000000000e-5
About Picofarads per metre
The picofarad per metre (pF/m) equals 10⁻¹² F/m, the most widely used permittivity scale. The vacuum permittivity ε₀ ≈ 8.854 pF/m; air at STP is ≈8.859 pF/m; PTFE PCB substrate is ≈19 pF/m; FR-4 laminate is ≈37 pF/m. Dielectric specifications in IPC-4101 and IEC 60250 list pF/m values. 1 pF/m = 10⁻¹² F/m.
About Nanofarads per centimetre
The nanofarad per centimetre (nF/cm) equals 10⁻⁷ F/m, used in power cable and high-voltage capacitor characterisation. High-voltage XLPE power cables (230 kV) have capacitance per unit length of 0.1-0.2 nF/cm; oil-impregnated paper capacitors used in power factor correction banks are characterised in nF/cm. 1 nF/cm = 10⁻⁷ F/m = 10³ pF/cm.
