(To do this, subtract the final exponent from the initial exponent.) There are a couple of special powers of ten that have their own prefix outside the ‘every three’ pattern. The metric system has prefix modifiers that are multiples of 10. Some prefixes are also used in digital communications and computer technology but they have a slightly different value because they are based on a power of 2. So there is no prefix for 10^-4 or 10^-8. It was only after the introduction of the metric system, the Greek ‘greater than one’ and Latin ‘less than one’ conversions went out of circulation.
