Just a convention? 10^3 a time?

Myria for ##10^4## and dimi for ##10^{-4}## have been in use in France until the middle of the 20th century.ppppparker said:or, why was one never adopted?

Today we use potentials of ##10## until ##1000## and then potentials of ##1000## which makes sense to cover the different orders we face. For everyday life we still have the small ones plus some special terms like hectares or acres.

The International System of Units (SI) only has prefixes for powers of 10 that are multiples of 3. Since 10^5 and 10^-5 are not multiples of 3, they do not have corresponding prefixes.

The SI system also does not have prefixes for powers of 10 that are less than 1. Therefore, there is no prefix for 10^4 and 10^-4.

While some people may use existing prefixes like "hecto" or "micro" to represent 10^5 and 10^-5, this is not officially recognized in the SI system. It is important to use standard units and prefixes in scientific communication.

Yes, instead of using a prefix, we can use scientific notation to represent 10^5 and 10^-5. For example, 10^5 can be written as 100,000 and 10^-5 can be written as 0.00001.

Prefixed units make it easier to express very large or very small numbers in a compact and standardized way. This is especially useful in scientific and technical fields where we often deal with numbers that are much larger or smaller than 1.
