What is a gilbert, and who was Gilbert?
The gilbert (G) is a unit for quantifying magnetomotive force, named after William Gilbert, an English scientist and physician born in 1544 who is regarded by many as the father of electricity and magnetism. An alternative measure of magnetomotive force is ampere turns (At); the gilbert (G) is a slightly smaller unit than the ampere turn. To convert from ampere turns to gilberts, multiply by 1.25664.
