affix notation. All prefixes argon applied to meters (m) as an example.



take away for kilo (k), any exponents greater than zero atomic number 18 capitalized, all less than zero are in lower fortune letters. If there are three letters, the first letter is of all time the prefix, the second two letters are the unit. If there are two letters, the first letter is a prefix if it is T,G,M,k,c,m,?,n,p, or f (usually), the second is always the entire unit or part of the unit. If there is only one letter, it is a unit. The rime preceding something measured using prefix notation may be in the ones, tens, or hundreds columns only. For example, 3.75 mA, 37.5 mA, or 375 mA are acceptable, but 0.375 mA or 3750 mA are not.
