It depends on what you're measuring it for!
Denier is the number most often used for filament silk yarns. It indicates the weight of a certain length of silk. The term comes from an ancient coin that was used to balance the silk scales. One denier is one gram per 9,000 meters of filament silk - sewing thread is usually around 125 - 150 denier, while a heavy buttonhole twist is usually 1000 denier or more. Denier is also used for nylon and other filament threads. With silk organzines, you often get a complex number - the first unit (sometimes with a d) is the weight of filament, the second number is the number of filaments per ply, and the final number is the number of plies. So a 21d10x2 organzine starts out with a 21 denier filament (finer than a hair) and twists together 10 of those to make the singles, and then 2 of the singles to make the yarn. To get the overall denier of the yarn, multiply the three numbers: 21x10x2=420, or about halfway between sewing thread and buttonhole twist. As the denier number goes up, the yarn gets thicker.
Many spun silk yarns are measured in a metric, or nm, scale - if you see a number with a slashmark in the middle, like 2/60, that is a two-ply silk yarn with each ply being 60 meters per gram. 2/60 is a fairly fine weaving yarn, and 2/10 is a medium-weight knitting yarn. As the last number goes up, the plies are smaller; as the first number goes up, the yarn has more plies, and is thicker. So if you have a 3/60, it would be the same weight as a 1/20.
If you're looking at weights of silk fabric, it's usually grams per meter. Some Habutai silks are measured in mm, or momme, which is a Japanese weight. 18-20 is lightweight, 21-28 is midweight, and above 28 is heavyweight.
Most silk yarns are either sold by weight (grams and kilograms, or pounds and ounces) or they're sold by yardage. Fabric is usually sold by yardage, but sometimes by weight if purchased in large amounts. Silk threads used for embroidery and sewing are usually sold by length - yards or meters.

Silk is often measured in denier. This is how many strands are in a square inch. This is a unit of thickness and quality - it is not a unit of weight.
I guess you could measure it is grams, or kilos for a huge quantity. Perhaps square metres would be a good idea?

The same units of weight of any material, since units do not depend on the specific material being measured.

Newtons(N). The unit should not change according to the material
