How many microhenries are in one henry?

One henry (1 H) equals exactly 1,000,000 microhenries (1,000,000 µH). The prefix "micro" means 10⁻⁶, so 1 H = 10⁶ µH.

Why are most RF inductors rated in microhenries rather than henries?

The henry is a large unit for practical electronics. RF coils and signal-path inductors typically range from a few nanohenries to a few hundred microhenries. Values in full henries are rare outside of power transformers and motor windings.

What is the difference between µH and uH?

They represent the same unit. "µH" uses the Greek letter mu (µ) for "micro", while "uH" is the ASCII-safe substitute used in software, datasheets, and schematics that cannot render the µ character.

Can I enter decimal values like 0.5 µH?

Yes. You can enter any positive number, including decimals such as 0.5 µH (= 0.0000005 H) or 1000 µH (= 0.001 H). The converter handles them correctly.

How many nanohenries are in one microhenry?

One microhenry equals exactly 1,000 nanohenries (1,000 nH). Nanohenries are three orders of magnitude smaller than microhenries.

Is this converter accurate for engineering calculations?

Yes. The conversion is a precise mathematical division with no approximation. Results are displayed with up to 6 significant figures to avoid floating-point display noise.

Summary

This converter translates inductance values from microhenries (µH) to henries (H) and all major inductance sub-units, including millihenries (mH) and nanohenries (nH). One henry equals exactly 1,000,000 microhenries. The henry is the SI base unit of inductance, but most practical inductors in RF and audio circuits are rated in microhenries or millihenries, making this conversion a frequent task in circuit design, filter calculations, and RF engineering.
