What this tool does
Calculate filament length to weight for a maker project. Cylindrical filament assumption; use actual density (PLA default 1.24 g/cm³) and measured diameter.
How to use the Filament Length to Weight Converter
- Enter or select filament length (meters).
- Enter or select filament diameter (mm).
- Enter or select material density (g/cm³).
- Read the calculated result; change any measurement to compare alternatives.
Formula
cross-section cm²=π×(diameter mm/20)²; grams per meter=area×100×density; length=mass/gramsPerMeter

Cylindrical filament assumption; use actual density (PLA default 1.24 g/cm³) and measured diameter.
No. Verify against the machine, tool and material manufacturer's instructions, especially for CNC feeds and speeds.
Measure actual material properties and machine usage, rather than relying on nominal default values.
Yes; your project inputs are never transmitted or stored by MasterTool.
