Hm, intressant läsning där:

The needle "system" is the "size" your machine uses. It is based on the overall length, the shank length, diameter, etc. ... There are many "system" sizes. Most, if not all, "industrial" or commercial machines use needles with a round shank. Most home machines need to have one flat side to the shank.
After you determine your system, the next "size" depends on the size thread you are using. This numbering system is usually expressed in 2 numbers, such as 120/19. The first number, 120 in this example, is the metric size. The second number, 19, is the number originated by Singer, sometimes referred to as the US size.
Here is a chart for needle selection based on thread size:
For Thread Size: Use Needle Size:
V-46 90/14, 100/16
V-69 100/16, 110/18, 120/19
V-92 120/19, 125/20, 130/21
V-138 125/20, 130/21, 140/22, 180/24

Nu är det bara dags att lyckas dechiffrera vad V-69 resp. V-92 är för trådtjocklek i den vanliga sifferserien här i landet...
