  • The wiktionary definition bugs me, because the 'SI UNIT' is the ampere.
    Hecto may be listed in the SI manual as a common prefix, but I've never seen people use 'hecto' in practice when dealing with electricity.

    Wiktionary's definition got mangled to '102' amps because someone used 10^2 exponent notation which normal people don't use for small numbers.

    Every electrical usage I've seen is that people stick to 'kilo' 'mega' and 'giga' , and milli, micro
