What are the types for strings, spool and twines?

Question

so up to this point I know strings are categorized in pounds such as 15 pounds, 40 pounds and such. what are the U.S. version of types, class, size number mean? at which store can I find a nylon string that's about 1.5mm to 2.5mm wide? thank you.

Answer 1

Working with string a lot for my hobby I have noticed there is no such thing as a conversion table that works for more than one make of string at most.

Best ask the store you buy from to measure the string.
According to my calculations 1/16" is just over 1.5mm, 3/32" is just under 2,5 mm. Most stores will be able to measure the string.

For many jobs string is sold to a strength, not a size, and size will differ with method of manufacturing, so you might need to actually measure the string rather than reading the label.

Shops that sell nylon string are, among others:
Fishing gear shops, very good on mono-filament string, some also have braided string.
Bead shops, mostly a selection on looks, not on strength.
Craft stores, (in the bead department.)
Ships chandlers, more likely braided string.
Yacht outfitters, braided string again, often in many colour variations.
Hardware stores. Look in the garden department, masonry department, and if they have that kind of department, hunting and fishing.
Cheap shops like dollar stores and oriental trading, pound shop and Action, not often, but if they have string it is likely to be much cheaper than any of the others.
