How many zeros are represented by the metric multiple prefix 'tera'?
Introduction to the metric system of smaller units or small numbers of larger units for a measurement. These units were generally defined as a convenient multiple of a smaller unit or a convenient division of a larger unit. Thus, in pre-revolutionary France, the inch was divided into 12 lines and each line was subdivided into 12 points. Similarly, astronomers introduced the light-year to describe large distances. The metric system on the other hand uses prefixes to denote multipliers of the one basic unit. For example, the prefix "kilo" is used to denote a multiplier of 1000; thus one kilometre is 1000 metres, one kilogram is
Metric prefix Metric prefix A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or fraction of the unit. While all metric prefixes in common use today are decadic, historically there have been a number of binary metric prefixes as well. Each prefix has a unique symbol that is prepended to the unit symbol. The prefix "kilo-", for example, may be added to "gram" to indicate "multiplication" by one thousand: one kilogram is equal to one thousand grams. The prefix "milli-", likewise, may be added to "metre" to indicate "division" by one thousand; one
