3D Printing Filament Length ↔ Weight Calculator
Instantly convert filament spool lengths to weight, or estimate remaining print length from a partially used spool.
Factual Answer: How much does PLA weigh?
How much does 3D printing filament weigh per meter? 1 meter of standard 1.75mm PLA filament weighs approximately 3 grams (specifically 2.98g, based on a PLA density of 1.24 g/cm³). For a standard 1kg (1000g) spool of 1.75mm PLA, the total length is approximately 335 meters.
