Convert filament length and weight
Pick the diameter and material, then enter a length or a weight: the other field updates automatically.
Reference (1 kg spool)
- PLA 1.75 mm ≈ 335 m
- PETG 1.75 mm ≈ 327 m
- ABS 1.75 mm ≈ 400 m
- Weight = length × cross-section × density
Example
| Input | Value |
|---|---|
| Diameter | 1.75 mm |
| Material | PLA (1.24) |
| Length | 330 m |
| Weight | ≈ 984 g |

Frequently asked questions
How do I go from length to weight?
Filament is a cylinder: weight = length × cross-section (π × radius²) × density. So diameter and material matter.
How many meters in 1 kg of 1.75 mm PLA?
About 335 m (density 1.24). PETG or ABS give different lengths.
Why does density change the result?
A denser material weighs more for the same length. PLA ≈ 1.24, ABS ≈ 1.04, PETG ≈ 1.27.
Is the calculation exact?
It assumes a constant diameter; real filament tolerances cause a small deviation.
