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, perm[`0degC`]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, perm.

  

 

  

The units of permeability are defined as follows.

  

A 0 degree Celsius perm is defined as approximately 5.721,3.510−10 kilogram per pascal square meter second.

  

A 23 degree Celsius perm is defined as approximately 5.745,2.510−10 kilogram per pascal square meter second.
