Millivatti

Millivatti is not an officially recognized unit in the International System of Units (SI). The term does not have a formal definition, symbol, or conversion rule in metrology, and it is not used in standard electrical engineering practice. In most technical contexts, millivolts (mV) or milliwatts (mW) are the correct descriptors for voltage and power, respectively.

Usage and interpretation of the term are informal and unclear, which is why it is generally discouraged in technical writing. When readers encounter “millivatti,” they may encounter one of several informal interpretations: some treat it as a playful or mnemonic stand‑in for millivolts, while others imagine it as a humorous unit for very small signal power. Because there is no consensus or official definition, the term can lead to ambiguity in measurements and reporting.

Origins of the word are uncertain, and it has appeared sporadically in hobbyist electronics discussions, vintage magazines, and online forums as a tongue‑in‑cheek way to express extremely small electrical quantities. It is not endorsed by standards bodies, and no standardized abbreviation or conversion exists.

In summary, millivatti is a nonstandard, informal term with no formal measurement meaning. Technical communication should rely on established units such as volts, millivolts, watts, or milliwatts, or use decibel representations for signal levels to avoid confusion.
