    noun
    Plural of thousandth.

    Note

    Only the fraction can be counted. The ordinal noun (the thousandth in a line) stays singular, and the adjective (the thousandth visitor) has no plural at all. So the plural always means equal parts out of a thousand, as in three thousandths of an inch or a margin of a few thousandths of a second. That makes it a unit of measure that is easy to count.
