Gilbert (Unit)

The gilbert (symbol: Gb) is an obsolete unit used in practical cgs and CGS-EMU systems to measure magnetomotive force.^[1] The unit is named for English physicist William Gilbert. Definition:

1 Gb = (1/4π) Bi-t

Conversion to the corresponding quantity in the SI, with the unit ampere-turn (A⋅t):

1 Gb ≘ (10/4π) A-turn ≈ 0.7957747 A⋅t^[1]
1 A-turn ≘ 4π × 10⁻¹ Gb^[1]
