Editing Chinese numerals (section)

===SI prefixes===
{{see also|Chinese units of measurement}}
In the People's Republic of China, the early translation for the [[SI prefix]]es in 1981 was different from those used today. The larger ({{zhi|c=兆}}, {{zhi|c=京}}, {{zhi|c=垓}}, {{zhi|c=秭}}, {{zhi|c=穰}}) and smaller Chinese numerals ({{zhi|c=微}}, {{zhi|c=纖}}, {{zhi|c=沙}}, {{zhi|c=塵}}, {{zhi|c=渺}}) were defined as translation for the SI prefixes as ''mega'', ''giga'', ''tera'', ''peta'', ''exa'', ''micro'', ''nano'', ''pico'', ''femto'', ''atto'', resulting in the creation of yet more values for each numeral.<ref name="PRC1981SIprefixes">{{in lang|zh}} [http://www.gov.cn/zwgk/2011-11/09/content_1989016.htm 1981 Gazette of the State Council of the People's Republic of China] {{Webarchive|url=https://web.archive.org/web/20120111151047/http://www.gov.cn/zwgk/2011-11/09/content_1989016.htm |date=2012-01-11 }}, [http://www.gov.cn/gongbao/shuju/1981/gwyb198118.pdf No. 365] {{Webarchive|url=https://web.archive.org/web/20141104042737/http://www.gov.cn/gongbao/shuju/1981/gwyb198118.pdf |date=2014-11-04 }}, page 575, Table 7: SI prefixes</ref>

The Republic of China (Taiwan) defined {{zhi|c=百萬}} as the translation for ''mega'' and {{zhi|c=兆}} as the translation for ''tera''. This translation is widely used in official documents, academic communities, informational industries, etc. However, the civil broadcasting industries sometimes use {{zhi|c=兆赫}} to represent "[[megahertz]]".

Today, the governments of both China and Taiwan use phonetic transliterations for the SI prefixes. However, the governments have each chosen different Chinese characters for certain prefixes. The following table lists the two different standards together with the early translation.
