Use the Inductance Converter
Inductance formula and what each symbol means
target = value × (factor of starting unit ÷ factor of target unit), where each factor is the unit value in H.
| Symbol | Meaning |
|---|---|
| value | The number you want to convert |
| factor | The unit’s size expressed in the base unit (H) |
Inductance examples
H to mH
10 H = 10,000 mH.
H to µH
10 H = 10,000,000 µH.
H to nH
10 H = 10,000,000,000 nH.
How to calculate Inductance step by step
- Choose the starting unit and the target unit.
- Enter your value.
- Read the converted value, plus the conversion factor in both directions.

How to read your Inductance result
The henry is the SI unit of inductance. Inductors in electronics are rated in millihenries, microhenries and nanohenries. Neighbouring prefixes differ by a factor of 1,000.
| UNIT | SYMBOL | EQUALS | VALUE OF 1 H |
|---|---|---|---|
| Henry | H | 1 H = 1 H | 1 H |
| Millihenry | mH | 1 mH = 0.001 H | 1,000 mH |
| Microhenry | µH | 1 µH = 0.000001 H | 1,000,000 µH |
| Nanohenry | nH | 1 nH = 1×10⁻⁹ H | 1,000,000,000 nH |
| Picohenry | pH | 1 pH = 1×10⁻¹² H | 1,000,000,000,000 pH |
| Kilohenry | kH | 1 kH = 1,000 H | 0.001 kH |
| Abhenry | abH | 1 abH = 1×10⁻⁹ H | 1,000,000,000 abH |
| Stathenry | statH | 1 statH = 898,755,180,000 H | 1.11265×10⁻¹² statH |
Common mistakes when calculating Inductance
- Mixing mH and µH, which differ by 1,000.
- Confusing inductance (H) with capacitance (F).
- Forgetting that nH is 1×10⁻⁹ H.
Inductance FAQ
How many µH is 1 mH?
1 mH is 1,000 µH.
How many nH is 1 µH?
1 µH is 1,000 nH.
What is a henry?
The inductance in which a current change of one ampere per second induces one volt.
What is the base unit for inductance?
This converter uses henry (H) as the common base unit: every value is first converted to it and then to the target unit.
How do I convert between two inductance units?
Choose the starting and target units, enter the value and read the result. By hand: convert to the base unit with the table, then divide by the target unit factor.
How many millihenries are in 1 henry?
1 H = 1,000 mH.
How many microhenries are in 1 henry?
1 H = 1,000,000 µH.
How many nanohenries are in 1 henry?
1 H = 1,000,000,000 nH.
Which inductance units does this converter support?
It covers 8 units: henry (H), millihenry (mH), microhenry (µH), nanohenry (nH), picohenry (pH), kilohenry (kH), abhenry (abH), stathenry (statH).
How accurate is the inductance converter?
Results are calculated at full double precision and shown to about 8 significant figures. Round the answer to the precision of your original measurement; a result cannot be more accurate than the number you started with.
