Inductance

Unit Conversion

Convert inductance units: henry, millihenry, and microhenry

The inductance of a coil is stated in henry (H), the SI unit. In practice, due to the small typical values, millihenry (mH) and microhenry (µH) are much more common.

Key conversion factors:

  • 1 henry (H) = 1,000 millihenry (mH)
  • 1 millihenry (mH) = 1,000 microhenry (µH)

Applications:

  • Electronics: sizing coils, chokes, and transformers
  • Filter design: designing LC resonant circuits

The inductance converter supports comparing electronic components and calculating resonant circuits.

Frequently asked questions about converting inductance

1 henry is a very large inductance for most electronic coils. Typical circuit components are in the millihenry or microhenry range, which is why these units are much more common in practice.

1 millihenry (mH) equals 1,000 microhenry (µH). This conversion matters when sizing coils in filter circuits, where different orders of magnitude are needed depending on the frequency range.

Inductance describes how strongly a coil opposes a change in current by generating a back-voltage. It's central to designing transformers, chokes, and LC resonant circuits in filter circuits.
