Margit is a Silver Reed (Studio) knitting machine dealer in Colorado. Her business is www.pacaknits.com.
I greatly appreciate active dealers like Margit who are knowledgeable and provide services for machine knitters. Margit has classes and parts. Margit is now the Silver Needles Cone Winder dealer. I have one of these wonderful machines, which I keep out and use regularly.
Margit recently wrote a useful essay about yarn weights which follows. I have a previous essay about yarn weights here: https://diananatters.blogspot.com/search?q=yarn+weight If you want to have an enjoyable, productive experience in machine knitting, choosing the right yarn is critical!

ARGH! Everyone seems to call yarn by different names using a confusing set of units! Hand knit and crochet, EU (Europe) vs. US, machine knit,
weaving WPP (wraps per inch), YPP (yards per pound), nm (meters per 1 gram – metric yarns number), … depending on the system you’re using,
16/2 = 2/24 = 6720 yds / lb (cotton count vs worsted count)
BTW, the basic conversions I know off the top of my head are:
• 2.54 cm = 1 inch
• 453.6 grams = 1 pound
• 1 kilogram (kg) = 2.2 pounds
Thank goodness for Google (and other search engines) and built in conversion computations. In the “old” days when I got my bachelor’s degree
in mathematics, we used the CRC Standard Mathematical Tables and Formulae. I don’t remember what version I used but much of this info is
available on calculators now.
What works with what machine? I’ve combined info from various web sites to provide basic guidelines. Please go to the sources listed below and
do your own research. When all else fails – SWATCH!! (I’m kidding – always always always make a gauge swatch for a knit item that requires
specific dimensions.)
Note: Silver Reed manuals have photos to correlate actual sizes of yarn to stitch dial settings and of course, the different gauge machines will
support different sizes of yarn. Yet more sets of numbers that have no relationship to the table below!
I did not include #6 (Super Bulky) and #7 (Jumbo) yarns as these generally cannot be used as main yarns in any machine. However, they may work
for weaving so keep your yarn stash!
3/11 = Sport Weight
4/8 = Worsted Weight
2/11and 3/15 = Fingering Weight
2/20 and 2/24 = Fine weight
2 strands of 2/24 together = Fingering Weight.
Here are some pertinent links:

Wikipedia Units of Textile Measurement
One nm equals 1,000 meters of yarn per kilogram (1,000 m/kg). This equals 50
meters per 50 grams. A 1/8 nm yarn (usually just called 1/8, without the nm)
tells you that the yarn has been spun 8 times longer than the standard and is
therefore finer. You will get 8,000 meters per kilogram if your yarn is a 1/8.
The first number in the name, or the 1 in 1/8 indicates the number of plies in
the yarn. A 1/8 yarn has one ply, a 2/8 yarn has 2 plies, etc.
A 2/8 yarn indicates the yarn was spun to 8,000 meters per kilogram, but then
plied into a two-ply yarn. The finished yarn will therefore measure 4,000
meters per kilogram.
A 3/8 yarn will have 2,666 meters/kilogram, or 8000
divided by 3.
How does the general numeric system compare to the CYCA chart? From thick
to thin:
- 4/8 yarn yields 1,120 yards per pound and is closest to what hand knitters
consider a DK weight yarn or #4.
- 3/8 yarn yields 1,490 yards per pound, or sport weight yarn. Similar to a DK
weight, but slightly thinner or #3.
- 2/8 yarn yields 2,240 yards per pound, for a fingering weight yarn or #2.
- 2/18 yarn yields 5,040 yards per pound and is considered laceweight or #0 -
#1.
- 2/20 yarn yields 5,600 yards per pound and is also considered laceweight. The
difference between 2/18 and 2/20 is slight for a hand knitter, akin to the
difference between 4/8 and 3/8.
- 2/24 yarn yields 5,960 yards per pound, and again, is considered laceweight.
