Nm – indirect method of measurement which represents the length of a thread in weight of one gram. The lower this value, the thicker
the thread. It can be calculated according to the formula "Nm = length in meters / weight in grams".
dtex – direct method of measurement which represents a weight of 10 000 meters of thread. The higher this value, the thicker the thread. It can be calculated according to the formula “dtex = weight of 10 000 meters of thread in grams”.
cN – a unit of measurement of the strength of a thread indicating the force to be applied to break the thread. The higher this value, the higher
the thread strength. 1000 cN is equivalent to ~1kg.
