How much does 100 meters of 1.75mm PETG filament weigh?
305.5 grams(approx. 0.305 kg)
100 meters of 1.75 mm PETG filament weighs approximately 305.5 grams due to PETG's higher density of 1.27 g/cm³.
Worked Mathematical Derivation
Key Formulation:
Length = 10,000 cm. Cross section = 0.02405 cm². Volume V = 240.53 cm³. Weight = 240.53 cm³ × 1.27 g/cm³ = 305.47 grams.Calculate Custom Weight or Length

Quick Rule of Thumb
Standard 1.75mm PLA yields approximately 330–335 meters per 1 kg spool. PETG yields ~327m, and ABS yields ~400m due to lower density.⚡

Frequently Asked Questions
How much does 100 meters of 1.75mm PETG filament weigh?
A standard 1 kg spool of PETG contains 305.5 grams (0.305 kg). Length = 10,000 cm. Cross section = 0.02405 cm². Volume V = 240.53 cm³. Weight = 240.53 cm³ × 1.27 g/cm³ = 305.47 grams.
How many hours of printing can you get from 1kg of PETG?
A 1kg spool typically yields between 40 and 80 hours of active printing time, depending on layer height, printing speed, and infill density (e.g. standard 50g models taking 3-4 hours each).
How much does an empty 1kg filament spool weigh?
An empty 1kg filament spool typically weighs between 190g and 260g. Cardboard spools (eSun, Polymaker) weigh ~200g-220g, while sturdy plastic spools (Bambu Lab, Prusament) weigh ~240g-250g.
Why does a 1kg spool of PETG have a different length than other plastics?
Filament length is inversely proportional to polymer density (L = Volume / Area, where Volume = Mass / Density). Lighter polymers like ABS (1.04 g/cm³) yield ~400 meters per kg, while denser materials like PLA (1.24 g/cm³) yield ~335 meters, and PETG (1.27 g/cm³) yields ~327 meters.
How many standard 3DBenchy boats can you print from 1kg of PETG?
A standard sliced 3DBenchy with 2 perimeters and 10% infill weighs approximately 11 to 13 grams. A full 1kg spool can print approximately 75 to 90 complete Benchy models without running out.
