Gilbert (unit)
From Infogalactic: the planetary knowledge core
Obsolete unit (Symbol: Gb) used in Practical cgs and emu cgs systems to measure magnetization.[1] The unit is named for English physicist William Gilbert.
Definition in magnetization
1 Gb = (1/4π)×Bi-turn
Conversion to A-turn
1 Gb = (10/4π) A-turn= 0.7957747 A-turn[1]
1 A-turn ≡ 4π * 10−1 Gb [1]
