I'm trying to calculate print cost based on how much filament was used. This would be very easy if a had a scale with precise measurements. So my question is has anyone calculated the weight per unit of length of filament. I'm using 1.75mm PLA material. Slic3r tells you how many mm of filament will be used in the print so all I need to know is how much a mm of 1.75mm PLA weighs to calculate the cost.

You can try this, [www.ic3dprinters.com], not sure how well it works. Just did a quick Google Search.
Otherwise, I would probably just print something. Weigh it to find out how many grams it is, then divide that by the length of filament Slic3r claimed you would use. You should be able to use the gram weight to find out how much the print cost you in filament, then use Slic3r's estimate to convert that cost to a filament length.
Round up to account for waste before and after the print, as well as failed prints.

find your print material volume, using your slice program.
enter your price of filament and it will tell you price per volume ( $30/kg PLA = 0.039000 $/cm3)
so if your slicing program tells you 5.8cm3 your price will be $ 0.2262

Volume and Mass is better to measure then length, as the density of material stays the same, but the width of the material varies...

My measurements of Faberdashery 1.75mm PLA:
Red - 312g/m
Buttercream - 3.08g/m
Blue - 3.06g/m
I made these measurements a couple of years ago along with empty spools so I could calculate how much was left on a spool at any time.
That only works if the spool contained exactly the stated amount. Would you be able to tell if some unscrupulous vendor put 10% less on there than claimed?
