Quick mH to µH answer
1 mH = 1,000 µH
multiply by 1,000
4.7 mH = 4,700 µH
millihenry to microhenry formula
Milli is 10^-3 and micro is 10^-6. They are three powers of ten apart, so every mH to µH conversion uses the exact factor 1,000.
µH = mH × 1,000
4.7 mH × 1,000 = 4,700 µHmH to µH table

Understanding millihenries and microhenries
When dealing with inductance, accuracy is paramount. The difference between a millihenry (mH) and a microhenry (µH) might seem small, but it represents a magnitude difference of one thousand. In scientific notation, a millihenry is expressed as 10⁻³, while a microhenry is 10⁻⁶ of the base unit (henry).
Converting from millihenries to microhenries is a standard mathematical operation across various technical fields, as they are commonly used for coils, filters, switching converters, RF circuits, and inductor datasheets. The conversion is always an exact multiple of 1,000, meaning you simply move the decimal point three places to the right (when converting milli to micro) or three places to the left (when converting micro to milli).
Because the metric system is based on powers of ten, learning how to quickly translate mH into µH (or vice-versa) can save valuable time in laboratory environments, engineering calculations, and academic research. We designed this mH to µH calculator to perform this exact transformation without any floating-point errors, ensuring that whether you are working with 4.7 mH or much larger figures, your final microhenry value is perfectly precise.
When to use mH vs µH
millihenries and microhenries are used for coils, filters, switching converters, RF circuits, and inductor datasheets. Use the larger milli unit when the number becomes easier to scan, and the smaller micro unit when you need finer detail.
