    A permille or per mille (Latin, literally meaning 'for (every) thousand') is a tenth of a percent or one part per thousand. It is written with the sign ‰ (Unicode U+2030)., which looks like a percent sign (%) with an extra 0 at the end. It is a stylized form of the three zeros in the denominator.

    1‰ = 10-3.

    For instance, 5‰ = 5/1000 = 0.005 = 0.5%

    [edit] Examples

    Examples of common use are:

    Blood alcohol content

    Seawater salinity. Eg "the average salinity is 35‰".

    When used to describe property taxation in the U.S., it is called the millage rate.
