Check if the spool has enough filament
Slicers quote meters; spools are sold by weight. Convert between them before a long print.

The job
A slicer estimates 87 m of filament; your spool says 1 kg but has been used. Weighing it and converting to meters is the only honest check before a multi-day print.
Material and diameter
Pick the filament type (density differs: PLA 1.24, PETG 1.27, ABS 1.04 g/cm³…) and the diameter (1.75, 2.85, or 3.0 mm). Enter grams or meters — the other side comes back with cost and spool estimates.
Worked example
One kg of 1.75 mm PLA runs ≈ 335 m; the same kg of 2.85 mm only ≈ 126 m because the cross-section is 2.65× larger. An 87 m print needs ~260 g of PLA — a half-used 1 kg spool might not make it.
Where it stops
Densities are typical values — composites like wood-fill or metal-fill are heavier. Empty spool weight (~120–150 g) must be subtracted from the scale reading first.
