3 unitsDetailed guide to Inductance
Inductance describes how strongly a conductor or coil resists changes in current by generating a magnetic field. It is a fundamental quantity in electromagnetics and circuit design.
The henry is the SI derived unit of inductance, while millihenries and microhenries are common in practical electronics and power applications.

What is inductance?
Inductance measures how much voltage is induced when current changes over time. A larger inductance produces a stronger opposition to rapid current change.
This effect is central to coils, chokes, transformers and many energy-conversion circuits.
Henries, millihenries and microhenries
One millihenry equals 0.001 henry, and one microhenry equals 0.000001 henry. These scaled units are far more practical for most real inductors.
Small signal and RF inductors often use microhenries, while larger coils and some filters may be expressed in millihenries.
Inductance in engineering practice
Inductance values are important in filter design, switching regulators, motor drives and transformer calculations.
Quick unit conversion helps when comparing datasheets, choosing replacement components and checking whether a design is using the intended order of magnitude.
