Milliampere-turn quick reference
| Milliampere-turn | Ampere-turn | Gilbert | Kiloampere-turn |
|---|---|---|---|
| 1 mAt | = 0.001 At | ≈ 0.001256637061 Gi | = 0.000001 kAt |
| 10 mAt | = 0.01 At | ≈ 0.01256637061 Gi | = 0.00001 kAt |
| 100 mAt | = 0.1 At | ≈ 0.1256637061 Gi | = 0.0001 kAt |
| 1000 mAt | = 1 At | ≈ 1.256637061 Gi | = 0.001 kAt |
Where the milliampere-turn fits
The next larger magnetomotive force unit is the gilbert (Gi). 1 mAt ≈ 0.001256637061 Gi, and 1 Gi ≈ 795.7747155 mAt.
