Yarn weight: N/M 13/3 (Romanian measurements), where N represents the kilometres of thread in a kilogram (so 13 kilometres / 1 kilogram) and M represents the numbers of strands which were wrapped together to make the finished thread (3 strands).

This is, actually, the Wt and Gunze count. The most common weight system specifies the length of the thread in kilometres required to weigh 1 kilogram. Therefore, a greater weight number (indicated in the American standard by the abbreviation wt) indicates a thinner, finer thread. The American standard of thread weight was adopted from the Gunze Count standard of Japan which uses two numbers separated by a forward slash. The first number corresponds to the wt number of the thread and the second number indicates how many strands of fiber were used to compose the finished thread. It is common to wrap three strands of the same weight to make one thread.
