  2. IUPAC numerical multiplier - Wikipedia

    en.wikipedia.org/wiki/IUPAC_numerical_multiplier

    The prefixes are given from the least significant decimal digit up: units, then tens, then hundreds, then thousands. For example: 548 → octa- (8) + tetraconta- (40) + pentacta- (500) = octatetracontapentacta-

  3. Numeral prefix - Wikipedia

    en.wikipedia.org/wiki/Numeral_prefix

    Nonetheless, for clarity, dictionaries list numerical prefixes in hyphenated form, to distinguish the prefixes from words with the same spellings (such as duo-and duo). Several technical numerical prefixes are not derived from words for numbers. (mega-is not derived from a number word, for example.) Similarly, some are only derived from words ...

  5. Power of 10 - Wikipedia

    en.wikipedia.org/wiki/Power_of_10

    m × 10 n. Or more compactly as: 10 n. This is generally used to denote powers of 10. Where n is positive, this indicates the number of zeros after the number, and where the n is negative, this indicates the number of decimal places before the number. As an example: 10 5 = 100,000 [1] 10 −5 = 0.00001 [2]

    "A base is a natural number B whose powers (B multiplied by itself some number of times) are specially designated within a numerical system." [1]: 38 The term is not equivalent to radix, as it applies to all numerical notation systems (not just positional ones with a radix) and most systems of spoken numbers. [1]

  8. Metric prefix - Wikipedia

    en.wikipedia.org/wiki/Metric_prefix

    As such, Richard J.C. Brown (who proposed the prefixes adopted for 10 ±27 and 10 ±30) has proposed a reintroduction of compound prefixes (e.g. kiloquetta-for 10 33) if a driver for prefixes at such scales ever materialises, with a restriction that the last prefix must always be quetta-or quecto-. This usage has not been approved by the BIPM ...
