Magnetomotive Force Converter
Magnetomotive force is the "driving force" that produces magnetic flux in a magnetic circuit, much as voltage drives current in an electrical one. The SI unit is the ampere-turn — the current in a coil multiplied by its number of turns. The gilbert is the older CGS unit.
1 Ampere-turn = 1.256637061 Gilbert
How to convert Ampere-turn to Gilbert
One Ampere-turn equals 1.256637061 Gilbert, so multiply any value in At by 1.256637061 to get Gi. To convert back, divide by 1.256637061 — or multiply by 0.7957747155.
Gi = At × 1.256637061
Example: 25 At × 1.256637061 = 31.41592654 Gi.
