Meaning and Definition
A unit of electrical capacitance equal to one trillionth (10⁻¹²) of a farad, now more commonly called a picofarad.
A historical term in electronics and electrical engineering for an extremely small unit of capacitance, used before the SI prefix 'pico-' became standard.
Dialectal Variation
British vs American Usage
Differences
No significant difference in usage; the term is equally obsolete in both varieties. The transition to 'picofarad' occurred in international scientific circles.
Connotations
Connotes outdated technical literature or the early-to-mid 20th century era of electronics.
Frequency
Extremely rare in contemporary use in both regions. Might be encountered by engineers or hobbyists restoring vintage equipment.

- Using it in new writing instead of 'picofarad'.
- Confusing it with 'microfarad' (which is a million times larger).
- Misspelling as 'micro microfarad'.
FAQ
Frequently Asked Questions
No, it is an obsolete term. The modern and internationally accepted unit is the picofarad (pF).
Before the SI prefix 'pico-' (10⁻¹²) was formally established, 'micro' (10⁻⁶) was doubled to indicate 10⁻¹². It was a practical, if non-systematic, naming convention.
They are a direct 1:1 equivalent. One micromicrofarad equals one picofarad. No numerical conversion is needed, only a change of unit name.
Primarily in electronics textbooks, schematics, or component catalogs from the early-to-mid 20th century, or in discussions about the history of electrical engineering.
A unit of electrical capacitance equal to one trillionth (10⁻¹²) of a farad, now more commonly called a picofarad.
Micromicrofarad is usually technical/historical in register.
Micromicrofarad: in British English it is pronounced /ˌmaɪkrəʊˌmaɪkrəʊˈfærəd/, and in American English it is pronounced /ˌmaɪkroʊˌmaɪkroʊˈfærəd/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: 'Micro' means small, so 'microMICROfarad' is a micro version of a microfarad—an incredibly tiny unit.
Conceptual Metaphor
A unit of capacitance as a container for electrical charge; a micromicrofarad is an almost unimaginably small container.
