Common Mistakes When Using “millifarad”
- Misspelling as 'milifarad' (one 'l').
- Confusing 'mF' (millifarad) with 'MF' or 'Mfd', which are old notations for microfarad.
- Pronouncing the 'i' in 'milli' as a long 'i' (/maɪlɪ/) instead of short (/mɪlɪ/).
FAQ
Frequently Asked Questions
It is a moderately large unit for practical capacitors. Everyday electronics more commonly use microfarads (μF, one millionth of a farad) or picofarads (pF, one trillionth). Millifarads are typical for power supply filtering or energy storage.
It is correctly abbreviated as 'mF'. Caution is needed, as 'MF' or 'Mfd' were historically used for microfarad, which can cause confusion.
Almost exclusively in electrical engineering, physics labs, electronics hobbyist projects, and technical component datasheets, particularly for electrolytic or supercapacitors.
A millifarad (mF) is 1000 times larger than a microfarad (μF). 1 mF = 1000 μF.
A unit of electrical capacitance equal to one thousandth of a farad.
Millifarad is usually technical / scientific in register.
Millifarad: in British English it is pronounced /ˈmɪlɪˌfærəd/, and in American English it is pronounced /ˈmɪləˌfɛrəd/. Tap the audio buttons above to hear it.

Mnemonic
Think of a MILLIon things? No, a MILLI-farad is one thousand times SMALLER than a farad. Remember: 'Milli' means 'thousandth', like millimetre.
Conceptual Metaphor
A CONTAINER METAPHOR: A millifarad measures the 'size' of an electrical 'bucket' for storing charge.
