Filament length to weight calculator

How many meters are left on that partial spool? How much does 5 meters weigh? Both directions update instantly. Pricing a print? Take the grams straight into the quote workspace.

How the conversion works

Filament volume is weight ÷ density, and length is volume divided by the strand's cross-section π × (diameter ÷ 2)². Editing either the weight or the length field recomputes the other. Densities used (g/cm³): PLA 1.24, PETG 1.27, ABS 1.04, ASA 1.07, TPU 1.21, Nylon 1.14, PC 1.20. Once you know the grams, the filament cost calculator turns them into money per print, and the print time cost calculator adds electricity and machine wear.
