Units of Inverse length Description

 • Inverse length has the dimension inverse length. The SI composite unit of inverse length is the inverse meter.
 • Maple knows the units of inverse length listed in the following table.

 Name Symbols Context Alternate Spellings Prefixes diopter standard * diopters, dioptre, dioptres SI kayser standard * kaysers SI

 An asterisk ( * ) indicates the default context, an at sign (@) indicates an abbreviation, and under the prefixes column, SI indicates that the unit takes all SI prefixes, IEC indicates that the unit takes IEC prefixes, and SI+ and SI- indicate that the unit takes only positive and negative SI prefixes, respectively.  Refer to a unit in the Units package by indexing the name or symbol with the context, for example, diopter[standard]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, diopter.
 The units of inverse length are defined as follows.
 A diopter is defined as an inverse meter.
 A kayser is defined as an inverse centimeter. Examples
