This denarius contained an average 4.5 grams, or 1 â 72 of a Roman pound of silver. It formed the backbone of Roman currency throughout the Roman republic. The denarius began to undergo slow debasement toward the end of the republican period.

It remained at nearly this weight until the time of Nero (AD 37-68), when it was reduced to 1 â 96 of a
Denier is a unit of measure for the linear mass density of fibers. It is defined as the mass in grams per 9,000 meters. In the International System of Units the tex is used instead (see below).The denier has its standard based in nature, a single strand of silk is one denier.ommes (mm) is a unit of weight traditionally used to measure the density of silk. It is similar to the use of thread count for cotton fabrics. Mommes express the weight in pounds, of a piece of material of size 45 inches by 100 yards. Silk is measured by weight either by grams or by momme (mm).
