About Ampere-turns
The ampere-turn (A·t) is the SI practical unit of magnetomotive force, defined as F = N × I (turns × current). A 100-turn relay coil at 10 mA produces 1 A·t; power transformer cores typically operate at 100-1000 A·t. 1 A·t = 1 A (turn is dimensionless in SI).
About Kiloampere-turns
The kiloampere-turn (kA·t) equals 10³ A·t. Standard engineering unit for industrial electromagnets and transformer windings - a 500-turn winding at 2 A produces 1 kA·t; MRI gradient coils are driven at tens of kA·t. 1 kA·t = 10³ A·t.
