Convert filament weight and length

Estimate how many metres are in a known filament weight, or how many grams a known length weighs. Choose a reference material and edit its density when your manufacturer provides a value.

Weight to convert (g)Length to convert (m)MaterialFilament diameter

Conversion estimate

1,000 g ≈ 335.3 m

Weight from entered length100 m ≈ 298.3 g

Density used1.24 g/cm³

Accuracy note

PLA and PETG densities are editable reference values. Pigments, fillers, foaming, diameter tolerance, and formulation can change the result. Use the manufacturer's datasheet value when available.
