This page converts microhenries into nanohenries using the factor 1000, and shows the reverse figure alongside it. Both units measure how strongly a coil opposes a change in current, which is why one number does the whole job.
One nano henry is one billionth of a henry (1e-9 henries). Microhenries are the range of RF chokes, switching-converter inductors and PCB trace inductance.
The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in nanohenries, so you can sanity-check whether your answer is a plausible size.
The formula
microhenries- The amount you are converting, in microhenries
1000- The exact number of nanohenries in one microhenry
nanohenries- The converted result
How it works, step by step
- Enter the value in microhenries.
- It is multiplied by 1000, the exact factor between the two units.
- The answer is shown in nanohenries, with the reverse conversion beneath it.
- Check the reference table if you want a figure of comparable size.
Worked examples
Buck converter inductor: 47 µH in nanohenries
Take buck converter inductor, roughly 47 µH. The conversion is a single multiplication — 47 × 1000 — giving 47,000 nH. Because the relationship is proportional, doubling the input doubles the answer to 94,000 nH.
Speaker crossover coil: 1500 µH in nanohenries
Take speaker crossover coil, roughly 1500 µH. The conversion is a single multiplication — 1500 × 1000 — giving 1.5e+06 nH. Because the relationship is proportional, doubling the input doubles the answer to 3e+06 nH.
How to read your score
Frequently asked questions
How many nanohenries are in one microhenry?
Exactly 1000. 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 nanohenries?
nanohenries = microhenries × 1000. Reversed, microhenries = nanohenries ÷ 1000, which is the same as multiplying by 0.001.
Which is the bigger unit, the microhenry or the nanohenry?
The microhenry. One microhenry equals 1000 nanohenries.
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 nanohenry?
One nano henry is one billionth of a henry (1e-9 henries).
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.
