One microhenry is exactly 1e-06 henries, so converting microhenries to henries is a single multiplication. Enter any figure and the result appears as you type — the arithmetic runs in your browser, so nothing is sent anywhere.
The henry is the SI unit of inductance: one volt induced per amp-per-second change in current. Microhenries are the range of RF chokes, switching-converter inductors and PCB trace inductance.
Two tables follow: rounded steps for quick lookup, and a set of real reference quantities converted into henries, which is usually more useful than the bare number.
The formula
microhenries- The amount you are converting, in microhenries
1e-06- The exact number of henries in one microhenry
henries- The converted result
How it works, step by step
- Enter the value in microhenries.
- It is multiplied by 1e-06, the exact factor between the two units.
- The answer is shown in henries, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
RF choke: 10 µH in henries
Take rf choke, roughly 10 µH. The conversion is a single multiplication — 10 × 1e-06 — giving 1e-05 H. Because the relationship is proportional, doubling the input doubles the answer to 2e-05 H.
PCB trace, 25 mm: 0.02 µH in henries
Take pcb trace, 25 mm, roughly 0.02 µH. The conversion is a single multiplication — 0.02 × 1e-06 — giving 2e-08 H. Because the relationship is proportional, doubling the input doubles the answer to 4e-08 H.

Frequently asked questions
How many henries are in one microhenry?
Exactly 1e-06. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert microhenries to henries?
henries = microhenries × 1e-06. Reversed, microhenries = henries ÷ 1e-06, which is the same as multiplying by 1,000,000.
Which is the bigger unit, the microhenry or the henry?
The henry. One microhenry is only 1e-06 of a henry, so it takes 1e+06 microhenries to make one henry.
What does this quantity actually measure?
Both units measure how strongly a coil opposes a change in current. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a microhenry?
Microhenries are the range of RF chokes, switching-converter inductors and PCB trace inductance.
What is a henry?
The henry is the SI unit of inductance: one volt induced per amp-per-second change in current.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
