These are the commonly used numerical prefixes in the English language, but most seem to have bases similar to words in European languages; e.g., French, Latin, and Greek. * These prefixes were declared in 2022 by the General Conference on Weights and Measures in Versailles, France.
† 1,000,000,000 is called "one billion" in the U.S., U.K., France (before May 3, 1961), Brazil, Puerto Rico, Greece, and in Italy, Russia and Turkey it is referred to as "one billion" when written out, but as "one milliard" when written as 109. 1,000,000,000,000 is called "one trillion" in the U.S., but is called "one billion" in Germany, the Netherlands, Austria, Sweden, Norway, Denmark, Finland, France (after May 3, 1961), Portugal, Poland. It is best to check for current definitions for each country to be certain to get it right, or better yet, just write it out numerically to avoid confusion. Thanks to Duncan for the zepto info.

About RF Cafe
Copyright: 1996 - 2024 Web BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
