Milliampert

Milliampert is not an officially recognized unit in the International System of Units (SI). In contemporary technical usage, it is typically seen as a misspelling or mispronunciation of milliampere, which is the standard submultiple of the ampere used to express small electric currents. The correct symbol for milliampere is mA, representing one thousandth of an ampere (10^-3 A).

Because milliampert has no formal definition in SI, it is not listed by standards bodies such as the International Bureau of Weights and Measures. When the term appears, it is generally safer to assume the writer intends milliampere or, less commonly, another current unit such as ampere (A) or microampere (µA), depending on context. The spelling with a terminal “t” is not established in technical literature and can result from typographical errors, transcription mistakes, or informal shorthand.

In practice, the use of milliampere is clear and standardized: currents are described in amperes or, more commonly for small currents, in milliamperes. If confronted with the term milliampert in a document, one should verify the intended magnitude by cross-checking values or consulting the author, as the term itself does not convey a defined quantity beyond the general implication of a small current.
