Convert Milliampere-turns to Femtoampere-turns
Convert Milliampere-turns (mA·t) to Femtoampere-turns (fA·t) instantly and accurately.
Conversion Formula
fA·t = mA·t × 1000000000000
About Milliampere-turns
The milliampere-turn (mA·t) equals 10⁻³ A·t. Practical unit for reed relays and small inductors - a typical reed relay operates at 20-100 mA·t; audio transformer cores for hearing aids are magnetised at a few mA·t. 1 mA·t = 10⁻³ A·t.
About Femtoampere-turns
The femtoampere-turn (fA·t) equals 10⁻¹⁵ A·t. Used in SQUID-based nanoscale magnetic sensor calibration and spintronics research where single-turn excitation loops carry femtoampere bias currents. 1 fA·t = 10⁻¹⁵ A·t.
