Formula to Convert Gilbert to Ampere-turn
The Gilbert is slightly smaller than the Ampere-turn. The conversion involves the factor $10/4\pi$.
The formula is:
$$1 \text{ Gb} \approx 0.7958 \text{ At}$$
Example
Convert 100 Gilbert to Ampere-turns:
$$100 \times 0.7958 = 79.58 \text{ At}$$

About the Units
The **Gilbert (Gb)** is the CGS unit of magnetomotive force (MMF), named after William Gilbert. The **Ampere-turn (At)** is the SI unit, representing the MMF produced by a direct current of one ampere flowing in a single-turn loop.
