1 millihenry = 1,000 microhenries
How it’s calculated
µH = mH × 1000
- Multiply the value in millihenries by 1000.
- To go back, divide by 1000 (or multiply by 0.001).
- 1 mH = 1,000 µH · 1 µH = 0.001 mH

Find the conversion factor
By definition 1 mH = 0.001 H and 1 µH = 0.000001 H, so 1 mH = 1000 µH. Source: BIPM SI Brochure (9th ed.) (SI prefixes and accepted units).
Multiply by the factor written as a fraction
Put mH in the denominator so it cancels, leaving µH.
Calculate (unrounded)
Round the answer
Rounded to 5 significant figures.
Answer: 1000 µH
1 mH in other units
Batch convert mH → µH
- 1 mH = 1000 µH
- 5 mH = 5000 µH
- 10 mH = 10000 µH
- 25 mH = 25000 µH

Frequently asked questions
Which inductance units can I convert?
henries (H), millihenries (mH), microhenries (µH), nanohenries (nH).
How accurate are the results?
Every unit is stored with its exact defining factor (NIST SP 811, NIST Handbook 44 or the BIPM SI Brochure). Calculations use double-precision arithmetic and are rounded only for display, to 5 significant figures by default (trailing zeros dropped, so 1 km shows as 1000 m). You can choose Auto (up to 10 digits), fixed decimals or more significant figures, or switch to scientific or engineering notation.
