Convert mH to nH
Type the number of millihenries that you wish to convert to nanohenries.
How to Convert Millihenries to Nanohenries
The millihenry and nanohenry are both units of inductance. By definition, 1 millihenry equals exactly 1e15 nanohenries. This means to convert millihenries to nanohenries, you multiply by 1e15.
Formula
Step-by-Step Example
Convert 5 mH to nanohenries:
We need to convert millihenries to nanohenries
Since 1 mH = 1e15 nH, multiply by 1e15
5 × 1e15 = 5e15
5 mH = 5e15 nH

About These Units
Millihenry (mH)
A millihenry (mH) equals 0.001 henries or 1,000 microhenries. Common for power inductors (1-100 mH), audio crossover coils (0.1-10 mH), EMI filter chokes, and relay coils. Speaker crossover inductors typically range from 0.5-5 mH.
Nanohenry (nH)
A nanohenry (nH) equals 10⁻⁹ henries or 1,000 picohenries. Used in high-frequency RF circuits (1-100 nH), chip inductors for cell phones, and microwave applications. SMD RF inductors: 1-100 nH. PCB trace inductance: ~1 nH per mm.
