If it had been written as a fractional inch, like your conversion, then there would have been no confusion, even with the units not stated!
Why is the packaging using decimal inches? Doesn't that make it hard to measure, inch rulers don't use decimals!
Still at it huh, Nigel? Always complaining about and criticizing any conventions that may be used in the USA that don't meet with your approval.
This is simply the sizing convention the trimmer industry has always used here to designate line diameters. Of course, as I've already pointed out, the packing as shown above also addresses your initial complaint about the metric system by listing the size in millimeters in addition to the decimal fractional equivalent but you conveniently ignore that aspect as it doesn't support your argument.
Let us also recall that you demonstrated your ignorance regarding string trimmers just yesterday when you revealed that like so many of the things you pontificate about, you have no personal experience with these machines. Indeed, nylon is rarely used nowadays as manufacturers have been gravitating towards other materials and biodegradable compounds.
I think you still need to fit some extra thick line or blades, the standard reasonably thin nylon line is supposed to avoid issues like that!
STIHL mentions in their literature, they offer trimmer line in all "
standard sizes" including .065, .080, .095, .105, .118, .120, .130, and .155 diameters.
One chooses the appropriate size to match their trimmer head and job requirements.
- Light: 0.065- to 0.080-inch line is best for trimming grass around the house and whacking down common lawn weeds from around driveways, walkways and fences.
- Medium: 0.080 to 0.110-inch line is best for homes with larger lawns, or gardens overgrown with weeds that have tough, heavy stems.
- Heavy: 0.110-inch and above. Professional landscapers pull this out for big jobs — large lots; commercial spaces; or lawns and gardens with thick grass, woody shrubs and dense underbrush.
