Frequently Asked Questions
How many grams does 1 meter of filament weigh?
Approximately 3.0 grams for standard 1.75 mm PLA (density 1.24 g/cm³). That is a useful reference, but the exact value depends on filament diameter and material density — use the calculator above for accurate results with your specific filament.
What is the formula to convert meters of filament to grams?
grams = meters × π × (diameter/2)² × density. For 1.75 mm PLA at 1.24 g/cm³, the factor is approximately 3.0 g/m. For denser materials like PETG (1.27 g/cm³) or thicker 2.85 mm filament, the weight per meter increases — always use material-specific values for precision.
Does this work for composite or filled filaments like carbon fibre PLA?
Yes, but use the correct density for the specific material. Carbon fibre PLA is typically 1.10–1.15 g/cm³ — lighter than standard PLA (1.24 g/cm³), so a spool contains more meters. Glow-in-the-dark PLA uses strontium aluminate filler and reaches around 1.5 g/cm³, meaning fewer meters per kilogram. Check the manufacturer's datasheet for accurate density values.
