3D Filament Calculator.
Convert filament volume or length into mass, cost and how many prints fit on a spool.
The filament is treated as a cylinder. Density presets are typical mid-range values. Cost uses the price per kilogram you enter. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
- Volume
- 100 cm³
- Length
- 41.575169 m
- Mass
- 124 g
- Cost

- Prints per spool
- 8.064516
Mass is volume times density. Length and volume use a round filament of the selected diameter. Density presets are typical mid-range values, and the price field is a label-free number.
How to use 3D Filament Calculator
Enter a volume from the slicer or a length, the filament diameter and a density.
How it works
Convert filament volume or length into mass, cost and how many prints fit on a spool. The filament is treated as a cylinder. Density presets are typical mid-range values. Cost uses the price per kilogram you enter. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
Example
100 cm³ of PLA at 1.24 g/cm³.
