It is common in technological areas if working with quantities in which their numerical representations are expressed in abbreviated form, these abbreviations follow multiplicative patterns called multiples and submultiples.
Example: 1. When working with mass we can use the Kg (Kilogram), which is the abbreviated representation of the standard unit g (gram), that is, the letter K used before the letter g (standard unit of mass quantity) is equivalent to 1000 grams.
2. When working with units measured in length, when measuring a piece that is 1mm (millimeter) long, this value will be the abbreviated representation of m (meter), its equivalence is 0.001 m (meter), because the "M" used before the letter m (meter) represents one-thousandth of a meter.
For each multiple or submultiple, a letter is designated to represent the abbreviated value obeying this a basic rule:
K - Kilo
M - Mega
G - Giga
m - Mili
μ- Micro
The abbreviated variation or representation is represented in such a way that each multiple or submultiple will have variation, comma indication, from 3 (three) to 3 (three) decimal places.
