Convert Femtoamperes per metre to Amperes per foot
Convert Femtoamperes per metre (fA/m) to Amperes per foot (A/ft) instantly and accurately.
Conversion Formula
A/ft = fA/m × 3.048000000e-16
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.
About Amperes per foot
The ampere per foot (A/ft) equals 1/0.3048 A/m ≈ 3.281 A/m. Used in US electromagnetic coil design and transformer winding specifications where dimensions are in feet; older US Navy and DoD magnetic shielding specifications for shipboard demagnetisation state H values in A/ft. 1 A/ft = 1/0.3048 A/m ≈ 3.2808 A/m.
