What Is This Tool?
This tool enables conversion of magnetomotive force values from the gilbert unit, used in older CGS-EMU systems, to the ampere turn unit, which is standard in modern SI electromagnetic applications.
How to Use This Tool?
-
Enter the magnetomotive force value in gilberts (Gi).
-
Select gilbert as the original unit and ampere turn as the target unit.
-
Click the convert button to get the equivalent value in ampere turns (At).
Key Features
-
Converts magnetomotive force from gilbert to ampere turn.
-
Uses accurate conversion based on the fixed relation 1 Gi = 0.7957747151 At.
-
Ideal for interpreting legacy or historical magnetomotive force data.
-
Web-based and simple to use without installation.
Examples
-
5 gilberts (Gi) equals approximately 3.9789 ampere turns (At).
-
10 gilberts (Gi) equals approximately 7.9577 ampere turns (At).
Common Use Cases
-
Translating historical magnetomotive force data to the SI unit system for compatibility.
-
Designing magnetic circuits, transformers, or inductors based on older electromagnetic measurements.
-
Calculating magnetizing forces for coils using legacy data in modern electrical engineering tasks.
Tips & Best Practices
-
Ensure the context of your data to confirm using gilbert is appropriate.
-
Double-check unit consistency when mixing CGS-EMU and SI unit systems.
-
Use this converter to improve accuracy when updating legacy magnetic circuit measurements.
Limitations
-
The gilbert is a largely outdated unit appearing mostly in historical documents.
-
Be aware of minor rounding differences arising from the use of π in the gilbert definition.
-
Always verify the applicability of gilbert units for your specific use case.
Frequently Asked Questions
-
What is the gilbert unit used for?
-
The gilbert is a CGS-EMU unit of magnetomotive force mainly used in older electromagnetic literature and legacy measurements.
-
How is an ampere turn defined?
-
An ampere turn represents magnetomotive force as the product of electric current in amperes and the number of turns in a coil.
-
Why convert gilbert to ampere turn?
-
Converting gilbert to ampere turn translates historical MMF data into SI units for modern electromagnetic design and analysis.
Key Terminology
-
Gilbert (Gi)
-
A CGS-EMU unit for magnetomotive force representing magnetic potential, equal to 10/(4π) ampere turns.
-
Ampere turn (At)
-
An SI unit of magnetomotive force defined as the product of electric current in amperes and coil turns.
-
Magnetomotive force (MMF)
-
The magnetic potential that drives magnetic flux in a magnetic circuit, analogous to electromotive force in electric circuits.
