Convert Kiloamperes per metre to Femtoamperes per metre
Convert Kiloamperes per metre (kA/m) to Femtoamperes per metre (fA/m) instantly and accurately.
Conversion Formula
fA/m = kA/m × 1.000000000e+18
About Kiloamperes per metre
The kiloampere per metre (kA/m) equals 10³ A/m. The primary practical unit for strong magnetic fields - MRI scanner bore fields of 1-3 T correspond to 800 kA/m-2.4 MA/m in free space; coercivity of hard ferrite permanent magnets (ceramic) is 150-300 kA/m; NdFeB magnets have coercivity 900-2000 kA/m. 1 kA/m = 10³ A/m ≈ 12.566 Oe.
About Femtoamperes per metre
The femtoampere per metre (fA/m) equals 10⁻¹⁵ A/m. Used in SQUID (superconducting quantum interference device) magnetometer research to characterise noise floors in ultra-sensitive magnetic field measurements; the Earth's geomagnetic DC drift and biomagnetic fields from neurons produce field gradients at the fA/m level in heavily shielded rooms. 1 fA/m = 10⁻¹⁵ A/m.
