Topic: linear messurement

I have always wondered why filamaent is sold by weight not by linear mesurement. If I buy a roll of most anything the amount is in inches, feet  ect.Just a random thought.

Re: linear messurement

Because selling by length would encourage suppliers to shave the diameter, selling filament that is actually 1.60mm or 1.65mm.

Selling by weight ensures you get what you paid for.

SO, I guess you won't know if it is 1KG unless you could weigh the new roll of the filament  and spool seperately lol That would be a pain tho to unspool a new roll. Maybe a comsumer reports project.

Weigh it when you get it, then weigh the empty spool when you're done if you're concerned.
