How to convert ampere-turns to gilberts
Magnetomotive force is current times number of turns; turn count is dimensionless. It is not magnetic flux, and a magnetic circuit model is needed to infer flux.
Use x for the value in A·turn, b for the intermediate value in A·turn, and y for the result in Gb.
Gb = A·turn ÷ 0.7957747154594768
Worked examples
10 A·turn ≈ 12.5663706144 Gb
Step 1: (10 × 1) ≈ 10 A·turn.
Step 2: 10 ÷ 0.795774715459 ≈ 12.5663706144 Gb.20 A·turn ≈ 25.1327412287 Gb
Step 1: (20 × 1) ≈ 20 A·turn.
Step 2: 20 ÷ 0.795774715459 ≈ 25.1327412287 Gb.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Ampere-turns
Ampere-turns (A·turn) measures magnetomotive force under the conventions above. The base value in A·turn is (x × 1), where x is the numerical value in A·turn. Factors shown here are rounded for display; calculations use the stored factor.
About Gilberts
Gilberts (Gb) measures magnetomotive force under the conventions above. The base value in A·turn is (x × 0.795774715459), where x is the numerical value in Gb. Factors shown here are rounded for display; calculations use the stored factor.
