How to convert ampere-turns to milliampere-turns
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 mA·turn.
mA·turn = A·turn ÷ 0.001
Worked examples
10 A·turn ≈ 10000 mA·turn
Step 1: (10 × 1) ≈ 10 A·turn.
Step 2: 10 ÷ 0.001 ≈ 10000 mA·turn.20 A·turn ≈ 20000 mA·turn
Step 1: (20 × 1) ≈ 20 A·turn.
Step 2: 20 ÷ 0.001 ≈ 20000 mA·turn.
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 Milliampere-turns
Milliampere-turns (mA·turn) measures magnetomotive force under the conventions above. The base value in A·turn is (x × 0.001), where x is the numerical value in mA·turn. Factors shown here are rounded for display; calculations use the stored factor.
